thr_getconcurrency(3C)					   Standard C Library Functions 				    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. Otherwise, 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.
