SYNOPSIS
#include
<pthread.h>
int
pthread_attr_getdetachstate
(const
pthread_attr_t *attr, int
*detachstate);
int
pthread_attr_setdetachstate
(pthread_attr_t
*attr, int
detachstate);
DESCRIPTION
The attribute parameters for thepthread_attr_getdetachstate
()
and
pthread_attr_setdetachstate
()
functions are mutually exclusive and must be one of:
PTHREAD_CREATE_JOINABLE
- The threads must explicitly be waited for using the pthread_join(3) function once they exit for their status to be received and their resources to be freed. This is the default.
PTHREAD_CREATE_DETACHED
- The thread's resources will automatically be freed once the thread exits, and the thread will not be joined.
If the thread is created as detached, it is an error to use the thread ID with pthread_detach(3) or pthread_join(3).
RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error.
ERRORS
No errors are defined for
pthread_attr_getdetachstate
().
The pthread_attr_setdetachstate
() function
should fail if:
- [
EINVAL
] - The value specified by detachstate is invalid.
