The new process image is constructed from a regular executable file called the new process image file. .Pp When a C program is executed as the result of this call, it is entered as a C-language function call as follows: .Bd -literal -offset indent int main(int argc, char *argv[]); .Ed .Pp where .Fa argc is the argument count and .Fa argv is an array of character pointers to the arguments themselves. In addition, the variable: .Bd -literal -offset indent extern char **environ; .Ed .Pp points to an array of character pointers to the environment strings. .Pp The argument .Fa argv is an array of character pointers to null-terminated strings. The last member of this array is a null pointer and is not counted in .Fa argc . These strings constitute the argument list available to the new process image. The value in .Fa argv Ns [0] should point to a filename that is associated with the process image being started by the .Fn posix_spawn or .Fn posix_spawnp function. .Pp The argument .Fa envp is an array of character pointers to null-terminated strings. These strings constitute the environment for the new process image. The environment array is terminated by a null pointer. .Pp The .Fa path argument to .Fn posix_spawn is a pathname that identifies the new process image file to execute. .Pp The .Fa file parameter to .Fn posix_spawnp is used to construct a pathname that identifies the new process image file. If the file parameter contains a slash character, the file parameter is used as the pathname for the new process image file. Otherwise, the path prefix for this file is obtained by a search of the directories passed as the environment variable .Dq Ev PATH . If this variable is not specified, the default path is set according to the .Dv _PATH_DEFPATH definition in .In paths.h , which is set to .Dq Ev /usr/bin:/bin . .Pp If .Fa file_actions is a null pointer, then file descriptors open in the calling process remain open in the child process, except for those whose close-on-exec flag .Dv FD_CLOEXEC is set (see .Fn fcntl ) . For those file descriptors that remain open, all attributes of the corresponding open file descriptions, including file locks (see .Fn fcntl ) , remain unchanged. .Pp If .Fa file_actions is not NULL, then the file descriptors open in the child process are those open in the calling process as modified by the spawn file actions object pointed to by .Fa file_actions and the .Dv FD_CLOEXEC flag of each remaining open file descriptor after the spawn file actions have been processed. The effective order of processing the spawn file actions are: .Bl -enum .It The set of open file descriptors for the child process initially are the same set as is open for the calling process. All attributes of the corresponding open file descriptions, including file locks (see .Fn fcntl ) , remain unchanged. .It The signal mask, signal default actions, and the effective user and group IDs for the child process are changed as specified in the attributes object referenced by .Fa attrp . .It The file actions specified by the spawn file actions object are performed in the order in which they were added to the spawn file actions object. .It Any file descriptor that has its .Dv FD_CLOEXEC flag set (see .Fn fcntl ) is closed. .El .Pp The .Vt posix_spawnattr_t spawn attributes object type is defined in .In spawn.h . It contains the attributes defined below. .Pp If the .Dv POSIX_SPAWN_SETPGROUP flag is set in the spawn-flags attribute of the object referenced by .Fa attrp , and the spawn-pgroup attribute of the same object is non-zero, then the child's process group is as specified in the spawn-pgroup attribute of the object referenced by .Fa attrp . .Pp As a special case, if the .Dv POSIX_SPAWN_SETPGROUP flag is set in the spawn-flags attribute of the object referenced by .Fa attrp , and the spawn-pgroup attribute of the same object is set to zero, then the child is in a new process group with a process group ID equal to its process ID. .Pp If the .Dv POSIX_SPAWN_SETPGROUP flag is not set in the spawn-flags attribute of the object referenced by .Fa attrp , the new child process inherits the parent's process group. .Pp If the .Dv POSIX_SPAWN_SETSCHEDPARAM flag is set in the spawn-flags attribute of the object referenced by .Fa attrp , but .Dv POSIX_SPAWN_SETSCHEDULER is not set, the new process image initially has the scheduling policy of the calling process with the scheduling parameters specified in the spawn-schedparam attribute of the object referenced by .Fa attrp . .Pp If the .Dv POSIX_SPAWN_SETSCHEDULER flag is set in the spawn-flags attribute of the object referenced by .Fa attrp (regardless of the setting of the .Dv POSIX_SPAWN_SETSCHEDPARAM flag), the new process image initially has the scheduling policy specified in the spawn-schedpolicy attribute of the object referenced by .Fa attrp and the scheduling parameters specified in the spawn-schedparam attribute of the same object. .Pp The .Dv POSIX_SPAWN_RESETIDS flag in the spawn-flags attribute of the object referenced by .Fa attrp governs the effective user ID of the child process. If this flag is not set, the child process inherits the parent process' effective user ID. If this flag is set, the child process' effective user ID is reset to the parent's real user ID. In either case, if the set-user-ID mode bit of the new process image file is set, the effective user ID of the child process becomes that file's owner ID before the new process image begins execution. .Pp The .Dv POSIX_SPAWN_RESETIDS flag in the spawn-flags attribute of the object referenced by .Fa attrp also governs the effective group ID of the child process. If this flag is not set, the child process inherits the parent process' effective group ID. If this flag is set, the child process' effective group ID is reset to the parent's real group ID. In either case, if the set-group-ID mode bit of the new process image file is set, the effective group ID of the child process becomes that file's group ID before the new process image begins execution. .Pp If the .Dv POSIX_SPAWN_SETSIGMASK flag is set in the spawn-flags attribute of the object referenced by .Fa attrp , the child process initially has the signal mask specified in the spawn-sigmask attribute of the object referenced by .Fa attrp . .Pp If the .Dv POSIX_SPAWN_SETSIGDEF flag is set in the spawn-flags attribute of the object referenced by .Fa attrp , the signals specified in the spawn-sigdefault attribute of the same object is set to their default actions in the child process. Signals set to the default action in the parent process is set to the default action in the child process. .Pp Signals set to be caught by the calling process is set to the default action in the child process. .Pp Signals set to be ignored by the calling process image is set to be ignored by the child process, unless otherwise specified by the .Dv POSIX_SPAWN_SETSIGDEF flag being set in the spawn-flags attribute of the object referenced by .Fa attrp and the signals being indicated in the spawn-sigdefault attribute of the object referenced by .Fa attrp . .Pp If the value of the .Fa attrp pointer is NULL, then the default values are used. .Pp All process attributes, other than those influenced by the attributes set in the object referenced by .Fa attrp as specified above or by the file descriptor manipulations specified in .Fa file_actions , appear in the new process image as though .Fn vfork had been called to create a child process and then .Fn execve had been called by the child process to execute the new process image. .Pp The implementation uses vfork(), thus the fork handlers are not run when .Fn posix_spawn or .Fn posix_spawnp is called. .Sh RETURN VALUES Upon successful completion, .Fn posix_spawn and .Fn posix_spawnp return the process ID of the child process to the parent process, in the variable pointed to by a non-NULL .Fa pid argument, and return zero as the function return value. Otherwise, no child process is created, no value is stored into the variable pointed to by .Fa pid , and an error number is returned as the function return value to indicate the error. If the .Fa pid argument is a null pointer, the process ID of the child is not returned to the caller. .Sh ERRORS .Bl -enum .It If .Fn posix_spawn and .Fn posix_spawnp fail for any of the reasons that would cause .Fn vfork or one of the .Nm exec to fail, an error value is returned as described by .Fn vfork and .Nm exec , respectively (or, if the error occurs after the calling process successfully returns, the child process exits with exit status 127). .It If .Nm POSIX_SPAWN_SETPGROUP is set in the spawn-flags attribute of the object referenced by attrp, and .Fn posix_spawn or .Fn posix_spawnp fails while changing the child's process group, an error value is returned as described by .Fn setpgid (or, if the error occurs after the calling process successfully returns, the child process exits with exit status 127). .It If .Nm POSIX_SPAWN_SETSCHEDPARAM is set and .Nm POSIX_SPAWN_SETSCHEDULER is not set in the spawn-flags attribute of the object referenced by attrp, then if .Fn posix_spawn or .Fn posix_spawnp fails for any of the reasons that would cause .Fn sched_setparam to fail, an error value is returned as described by .Fn sched_setparam (or, if the error occurs after the calling process successfully returns, the child process exits with exit status 127). .It If .Nm POSIX_SPAWN_SETSCHEDULER is set in the spawn-flags attribute of the object referenced by attrp, and if .Fn posix_spawn or .Fn posix_spawnp fails for any of the reasons that would cause .Fn sched_setscheduler to fail, an error value is returned as described by .Fn sched_setscheduler (or, if the error occurs after the calling process successfully returns, the child process exits with exit status 127). .It If the .Fa file_actions argument is not NULL, and specifies any dup2 or open actions to be performed, and if .Fn posix_spawn or .Fn posix_spawnp fails for any of the reasons that would cause .Fn dup2 or .Fn open to fail, an error value is returned as described by .Fn dup2 and .Fn open , respectively (or, if the error occurs after the calling process successfully returns, the child process exits with exit status 127). An open file action may, by itself, result in any of the errors described by .Fn dup2 , in addition to those described by .Fn open .

This transformation is as if the specified sequence of actions was performed exactly once, in the context of the spawned process (prior to execution of the new process image), in the order in which the actions were added to the object; additionally, when the new process image is executed, any file descriptor (from this new set) which has its .Dv FD_CLOEXEC flag set is closed (see .Fn posix_spawn ) . .Pp The .Fn posix_spawn_file_actions_addopen function adds an open action to the object referenced by .Fa file_actions that causes the file named by .Fa path to be opened (as if .Bd -literal -offset indent open(path, oflag, mode) .Ed .Pp had been called, and the returned file descriptor, if not .Fa fildes , had been changed to .Fa fildes ) when a new process is spawned using this file actions object. If .Fa fildes was already an open file descriptor, it is closed before the new file is opened. .Pp The string described by .Fa path is copied by the .Fn posix_spawn_file_actions_addopen function. .Pp The .Fn posix_spawn_file_actions_adddup2 function adds a dup2 action to the object referenced by .Fa file_actions that causes the file descriptor .Fa fildes to be duplicated as .Fa newfildes (as if .Bd -literal -offset indent dup2(fildes, newfildes) .Ed .Pp had been called) when a new process is spawned using this file actions object, except that the .Dv FD_CLOEXEC flag for .Fa newfildes is cleared even if .Fa fildes is equal to .Fa newfildes . The difference from .Fn dup2 is useful for passing a particular file descriptor to a particular child process. .Pp The .Fn posix_spawn_file_actions_addclose function adds a close action to the object referenced by .Fa file_actions that causes the file descriptor .Fa fildes to be closed (as if .Bd -literal -offset indent close(fildes) .Ed .Pp had been called) when a new process is spawned using this file actions object. .Sh RETURN VALUES Upon successful completion, these functions return zero; otherwise, an error number is returned to indicate the error. .Sh ERRORS These functions fail if: .Bl -tag -width Er .It Bq Er EBADF The value specified by .Fa fildes or .Fa newfildes is negative. .It Bq Er ENOMEM Insufficient memory exists to add to the spawn file actions object. .El .Sh SEE ALSO .Xr close 2 , .Xr dup2 2 , .Xr open 2 , .Xr posix_spawn 3 , .Xr posix_spawn_file_actions_destroy 3 , .Xr posix_spawn_file_actions_init 3 , .Xr posix_spawnp 3 .Sh STANDARDS The .Fn posix_spawn_file_actions_addopen , .Fn posix_spawn_file_actions_adddup2 and .Fn posix_spawn_file_actions_addclose functions conform to .St -p1003.1-2001 , with the exception of the behavior of .Fn posix_spawn_file_actions_adddup2 if .Fa fildes is equal to .Fa newfildes (clearing .Dv FD_CLOEXEC ) .
