NAME

12       pthread_self - get the calling thread ID
13

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

26

ERRORS

28       No errors are defined.

RATIONALE

41       The  pthread_self()  function provides a capability similar to the get‐
42       pid() function for processes and the rationale is the  same:  the  cre‐
43       ation call does not provide the thread ID to the created thread.
44

FUTURE DIRECTIONS

46       None.
