Legal values for .Fa state are .Dv PTHREAD_CANCEL_ENABLE and .Dv PTHREAD_CANCEL_DISABLE . .Pp The .Fn pthread_setcanceltype function atomically both sets the calling thread's cancelability type to the indicated .Fa type and, if .Fa oldtype is not .Dv NULL , returns the previous cancelability type at the location referenced by .Fa oldtype . Legal values for .Fa type are .Dv PTHREAD_CANCEL_DEFERRED and .Dv PTHREAD_CANCEL_ASYNCHRONOUS . .Pp The cancelability state and type of any newly created threads, including the thread in which .Fn main was first invoked, are .Dv PTHREAD_CANCEL_ENABLE and .Dv PTHREAD_CANCEL_DEFERRED respectively. .Pp The .Fn pthread_testcancel function creates a cancellation point in the calling thread. The .Fn pthread_testcancel function has no effect if cancelability is disabled. .Pp .Ss Cancelability States The cancelability state of a thread determines the action taken upon receipt of a cancellation request. The thread may control cancellation in a number of ways. .Pp Each thread maintains its own .Dq cancelability state which may be encoded in two bits: .Bl -hang .It Em Cancelability Enable When cancelability is .Dv PTHREAD_CANCEL_DISABLE , cancellation requests against the target thread are held pending. .It Em Cancelability Type When cancelability is enabled and the cancelability type is .Dv PTHREAD_CANCEL_ASYNCHRONOUS , new or pending cancellation requests may be acted upon at any time. When cancelability is enabled and the cancelability type is .Dv PTHREAD_CANCEL_DEFERRED , cancellation requests are held pending until a cancellation point (see below) is reached. If cancelability is disabled, the setting of the cancelability type has no immediate effect as all cancellation requests are held pending; however, once cancelability is enabled again the new type will be in effect. .El .Ss Cancellation Points Cancellation points will occur when a thread is executing the following functions: .Bl -tag -width "Fn pthread_cond_timedwait" -compact .It Fn accept .It Fn accept4 .It Fn aio_suspend .It Fn connect +.It Fn clock_nanosleep .It Fn close .It Fn creat .It Fn fcntl The .Fn fcntl function is a cancellation point if .Fa cmd is .Dv F_SETLKW . .It Fn fdatasync .It Fn fsync .It Fn kevent The .Fn kevent function is a cancellation point if it is potentially blocking, such as when the .Fa nevents argument is non-zero. .It Fn mq_receive .It Fn mq_send .It Fn mq_timedreceive .It Fn mq_timedsend .It Fn msync .It Fn nanosleep .It Fn open .It Fn openat .It Fn pause .It Fn poll .It Fn ppoll .It Fn pselect .It Fn pthread_cond_timedwait .It Fn pthread_cond_wait .It Fn pthread_join .It Fn pthread_testcancel .It Fn read .It Fn readv .It Fn recv .It Fn recvfrom .It Fn recvmsg .It Fn select .It Fn sem_timedwait .It Fn sem_clockwait_np .It Fn sem_wait .It Fn send .It Fn sendmsg .It Fn sendto .It Fn sigsuspend .It Fn sigtimedwait .It Fn sigwaitinfo .It Fn sigwait .It Fn sleep .It Fn system .It Fn tcdrain .It Fn usleep .It Fn wait .It Fn wait3 .It Fn wait4 .It Fn wait6 .It Fn waitid .It Fn waitpid .It Fn write .It Fn writev .El .Sh NOTES The .Fn pthread_setcancelstate and .Fn pthread_setcanceltype functions are used to control the points at which a thread may be asynchronously canceled. For cancellation control to be usable in modular fashion, some rules must be followed. .Pp For purposes of this discussion, consider an object to be a generalization of a procedure. It is a set of procedures and global variables written as a unit and called by clients not known by the object. Objects may depend on other objects. .Pp First, cancelability should only be disabled on entry to an object, never explicitly enabled. On exit from an object, the cancelability state should always be restored to its value on entry to the object. .Pp This follows from a modularity argument: if the client of an object (or the client of an object that uses that object) has disabled cancelability, it is because the client does not want to have to worry about how to clean up if the thread is canceled while executing some sequence of actions. If an object is called in such a state and it enables cancelability and a cancellation request is pending for that thread, then the thread will be canceled, contrary to the wish of the client that disabled. .Pp Second, the cancelability type may be explicitly set to either .Em deferred or .Em asynchronous upon entry to an object. But as with the cancelability state, on exit from an object that cancelability type should always be restored to its value on entry to the object. .Pp Finally, only functions that are cancel-safe may be called from a thread that is asynchronously cancelable. .Sh RETURN VALUES If successful, the .Fn pthread_setcancelstate and .Fn pthread_setcanceltype functions will return zero. Otherwise, an error number shall be returned to indicate the error. .Sh ERRORS The function .Fn pthread_setcancelstate may fail with: .Bl -tag -width Er .It Bq Er EINVAL The specified state is not .Dv PTHREAD_CANCEL_ENABLE or .Dv PTHREAD_CANCEL_DISABLE . .El .Pp The function .Fn pthread_setcanceltype may fail with: .Bl -tag -width Er .It Bq Er EINVAL The specified state is not .Dv PTHREAD_CANCEL_DEFERRED or .Dv PTHREAD_CANCEL_ASYNCHRONOUS . .El .Sh SEE ALSO .Xr pthread_cancel 3 .Sh STANDARDS The .Fn pthread_testcancel function conforms to .St -p1003.1-96 . The standard allows implementations to make many more functions cancellation points. .Sh AUTHORS This manual page was written by .An David Leonard Aq Mt d@openbsd.org for the .Ox implementation of .Xr pthread_cancel 3 .
