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.
STANDARDS
The
pthread_detach() function conforms to ISO/IEC 9945-1:1996 (“POSIX.1”).
