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

None.
