THR_GETCONCURRENCY(3C)					THR_GETCONCURRENCY(3C)

NAME
       thr_getconcurrency,  thr_setconcurrency - get or set thread concurrency
       level

SYNOPSIS
       cc -mt [ flag... ] file...[ library... ]
       #include <thread.h>

       int thr_setconcurrency(int new_level);

       int thr_getconcurrency(void);

DESCRIPTION
       These functions are obsolete and	 maintained  for  compatibility	 only.
       The thr_setconcurrency() function updates the desired concurrency level
       that libthread maintains for the calling process. This value  does  not
       affect the behavior of the calling process.

       The  thr_getconcurrency()  function  returns  the current value for the
       desired concurrency level.

RETURN VALUES
       The thr_getconcurrency() function always returns the current value  for
       the desired concurrency level.

       If  successful,	the  thr_setconcurrency() function returns  0.	Other‐
       wise, a non-zero value is returned to indicate the error.

ERRORS
       The  thr_setconcurrency() function will fail if:

       EAGAIN
		  The  specified  concurrency  level  would  cause  a	system
		  resource to be exceeded.

       EINVAL
		  The value for new_level is negative.
