pthread_detach

pthread_detach(3T)														pthread_detach(3T)

NAME

       pthread_detach() - mark a thread as detached to reclaim its resources when it terminates

SYNOPSIS

PARAMETERS

	      thread	Thread whose resources are to be reclaimed immediately when it terminates.

DESCRIPTION

       is  used  to detach the thread thread.  When thread terminates, its resources will automatically be reclaimed by the system.  If thread has
       already terminated, causes the resources of thread to be reclaimed by the system.

       does not cause thread to terminate.

       Once a detached thread has terminated, its resources, including the thread ID, may be reused by the system. The return status of a detached
       thread is lost when the thread terminates.

       Calling this function multiple times for the same thread results in undefined behavior.

RETURN VALUE

       Upon successful completion, returns zero. Otherwise, an error number is returned to indicate the error (the variable is not set).

ERRORS

       If any of the following occur, the function returns the corresponding error number:

	      [EINVAL]	     thread does not refer to a joinable thread.

	      [ESRCH]	     No thread could be found corresponding to thread.

AUTHOR

       was derived from the IEEE POSIX P1003.1c standard.
