The stream is positioned at the beginning of the file. Fail if the file does not exist. .It Dq Li w Open for writing. The stream is positioned at the beginning of the file. Create the file if it does not exist. .It Dq Li a Open for writing. The stream is positioned at the end of the file. Subsequent writes to the file will always end up at the then current end of file, irrespective of any intervening .Xr fseek 3 or similar. Create the file if it does not exist. .El .Pp An optional .Dq Li + following .Dq Li r , .Dq Li w , or .Dq Li a opens the file for both reading and writing. An optional .Dq Li x following .Dq Li w or .Dq Li w+ causes the .Fn fopen call to fail if the file already exists. .Pp The .Fa mode string can also include the letter .Dq Li b after either the .Dq Li + or the first letter. This is strictly for compatibility with .St -isoC -and has no effect; the ``b'' is ignored. +and has effect only for +.Fn fmemopen +; otherwise the ``b'' is ignored. .Pp Any created files will have mode .Do Dv S_IRUSR \&| .Dv S_IWUSR \&| .Dv S_IRGRP \&| .Dv S_IWGRP \&| .Dv S_IROTH \&| .Dv S_IWOTH Dc .Pq Li 0666 , as modified by the process' umask value (see .Xr umask 2 ) . .Pp Reads and writes may be intermixed on read/write streams in any order, and do not require an intermediate seek as in previous versions of .Em stdio . This is not portable to other systems, however; .Tn ANSI C requires that a file positioning function intervene between output and input, unless an input operation encounters end-of-file. .Pp The .Fn fdopen function associates a stream with the existing file descriptor, .Fa fildes . The mode of the stream must be compatible with the mode of the file descriptor. The .Dq Li x mode option is ignored. When the stream is closed via .Xr fclose 3 , .Fa fildes is closed also. .Pp The .Fn freopen function opens the file whose name is the string pointed to by .Fa path and associates the stream pointed to by .Fa stream with it. The original stream (if it exists) is closed. The .Fa mode argument is used just as in the .Fn fopen function. .Pp If the .Fa path argument is .Dv NULL , .Fn freopen attempts to re-open the file associated with .Fa stream with a new mode. The new mode must be compatible with the mode that the stream was originally opened with: Streams open for reading can only be re-opened for reading, streams open for writing can only be re-opened for writing, and streams open for reading and writing can be re-opened in any mode. The .Dq Li x mode option is not meaningful in this context. .Pp The primary use of the .Fn freopen function is to change the file associated with a standard text stream .Dv ( stderr , stdin , or .Dv stdout ) . +.Pp +The +.Fn fmemopen +function +associates the buffer given by the +.Fa buf +and +.Fa size +arguments with a stream. +The +.Fa buf +argument is either a null pointer or point to a buffer that +is at least +.Fa size +bytes long. +If a null pointer is specified as the +.Fa buf +argument, +.Fn fmemopen +allocates +.Fa size +bytes of memory. This buffer is automatically freed when the +stream is closed. Buffers can be opened in text-mode (default) or binary-mode +(if ``b'' is present in the second or third position of the +.Fa mode +argument). Buffers opened in text-mode make sure that writes are terminated with +a NULL byte, if the last write hasn't filled up the whole buffer. Buffers +opened in binary-mode never append a NULL byte. .Sh RETURN VALUES Upon successful completion .Fn fopen , .Fn fdopen and .Fn freopen return a .Tn FILE pointer. Otherwise, .Dv NULL is returned and the global variable .Va errno is set to indicate the error. .Sh ERRORS .Bl -tag -width Er .It Bq Er EINVAL The .Fa mode argument to .Fn fopen , .Fn fdopen , +.Fn freopen , or -.Fn freopen +.Fn fmemopen was invalid. .El .Pp The .Fn fopen , -.Fn fdopen -and +.Fn fdopen , .Fn freopen +and +.Fn fmemopen functions may also fail and set .Va errno for any of the errors specified for the routine .Xr malloc 3 . .Pp The .Fn fopen function may also fail and set .Va errno for any of the errors specified for the routine .Xr open 2 . .Pp The .Fn fdopen function may also fail and set .Va errno for any of the errors specified for the routine .Xr fcntl 2 . .Pp The .Fn freopen function may also fail and set .Va errno for any of the errors specified for the routines .Xr open 2 , .Xr fclose 3 and .Xr fflush 3 . .Sh SEE ALSO .Xr open 2 , .Xr fclose 3 , .Xr fileno 3 , .Xr fseek 3 , .Xr funopen 3 .Sh STANDARDS The .Fn fopen and .Fn freopen functions conform to .St -isoC , with the exception of the .Dq Li x mode option which conforms to .St -isoC-2011 . The .Fn fdopen function conforms to .St -p1003.1-88 . +The +.Fn fmemopen +function +conforms to +.St -p1003.1-2008 . +The ``b'' mode does not conform to any standard +but is also supported by glibc.
