NAME

13       pthread_self — get the calling thread ID
14

SYNOPSIS

16       #include <pthread.h>
17
18       pthread_t pthread_self(void);
19

DESCRIPTION

21       The pthread_self() function shall return the thread ID of  the  calling
22       thread.
23

RETURN VALUE

25       The  pthread_self()  function  shall always be successful and no return
26       value is reserved to indicate an error.
27

ERRORS

29       No errors are defined.

31       The following sections are informative.

EXAMPLES

34       None.
35

APPLICATION USAGE

37       None.
38

RATIONALE

40       The pthread_self() function provides a capability similar to  the  get‐
41       pid()  function  for  processes and the rationale is the same: the cre‐
42       ation call does not provide the thread ID to the created thread.
43

FUTURE DIRECTIONS

45       None.
