.SH 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.
.SH NAME

\fB#include <pthread.h>
.br
.sp

\fP
.SH DESCRIPTION
.LP
The \fIpthread_self\fP() function shall return the thread ID of the
calling thread.
.SH RETURN VALUE
.LP
Refer to the DESCRIPTION.
.SH ERRORS
.LP
No errors are defined.

.SH EXAMPLES
.LP
None.
.SH APPLICATION USAGE
.LP
None.
.SH RATIONALE
.LP
The \fIpthread_self\fP() function provides a capability similar to
the \fIgetpid\fP()
function for processes and the rationale is the same: the creation
call does not provide the thread ID to the created thread.
.SH FUTURE DIRECTIONS
.LP
None.
