PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing 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

       Refer to the DESCRIPTION.

ERRORS

       No errors are defined.

       The pthread_self() function shall not return an error code of [EINTR].

       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  cre-
       ation call does not provide the thread ID to the created thread.

FUTURE DIRECTIONS

       None.
