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

PROLOG         top

       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         top

       pthread_self — get the calling thread ID

SYNOPSIS         top

       #include <pthread.h>

       pthread_t pthread_self(void);

DESCRIPTION         top

       The pthread_self() function shall return the thread ID of the
       calling thread.

RETURN VALUE         top

       The pthread_self() function shall always be successful and no
       return value is reserved to indicate an error.

ERRORS         top

       No errors are defined.

       The following sections are informative.

EXAMPLES         top

       None.

APPLICATION USAGE         top

       None.

RATIONALE         top

       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         top

       None.
