PTHREAD_SELF(3P)            POSIX Programmer's Manual           PTHREAD_SELF(3P)



PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the corresponding
       Linux manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

NAME
       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
       None.

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.
