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.
