pthread_detach

PTHREAD_DETACH(3)					   BSD Library Functions Manual 					 PTHREAD_DETACH(3)

NAME

     pthread_detach -- detach a thread

LIBRARY

     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS

     #include <pthread.h>

     int
     pthread_detach(pthread_t thread);

DESCRIPTION

     The pthread_detach() function is used to indicate to the implementation that storage for the thread thread can be reclaimed when the thread
     terminates.  If thread has not terminated, pthread_detach() will not cause it to terminate.  The effect of multiple pthread_detach() calls on
     the same target thread is unspecified.

RETURN VALUES

     If successful, the pthread_detach() function will return zero.  Otherwise an error number will be returned to indicate the error.	Note that
     the function does not change the value of errno as it did for some drafts of the standard.  These early drafts also passed a pointer to
     pthread_t as the argument.  Beware!

ERRORS

     The pthread_detach() function will fail if:

     [EINVAL]		The implementation has detected that the value specified by thread does not refer to a joinable thread.

     [ESRCH]		No thread could be found corresponding to that specified by the given thread ID, thread.

SEE ALSO

     pthread_join(3)

STANDARDS

     The pthread_detach() function conforms to ISO/IEC 9945-1:1996 (``POSIX.1'').
