pthread_detach(3THR)

pthread_detach(3THR) is an alternative to pthread_join(3THR) to reclaim storage for a thread that is created with a detachstate attribute set to PTHREAD_CREATE_JOINABLE.

Prototype:
int	pthread_detach(thread_t tid);

#include <pthread.h>

pthread_t tid;
int ret;

/* detach thread tid */
ret = pthread_detach(tid); 

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

Return Values

pthread_detach() returns zero when it completes successfully. Any other return value indicates that an error occurred. When any of the following conditions is detected, pthread_detach() fails and returns the corresponding value.

EINVAL

tid is not a valid thread.

ESRCH

tid is not a valid, undetached thread in the current process.
