pthread_self — get the calling thread ID

SYNOPSIS

#include <pthread.h>
pthread_t pthread_self(void);

DESCRIPTION

The pthread_self() function shall return the thread ID of the calling thread.

RETURN VALUE

The pthread_self() function shall always be successful and no return value is reserved to indicate an error.

ERRORS

No errors are defined.

The following sections are informative.

EXAMPLES

None.

APPLICATION USAGE

RATIONALE

The pthread_self() function provides a capability similar to the getpid() function for processes and the rationale is the same: the creation call does not provide the thread ID to the created thread.

FUTURE DIRECTIONS

None.
