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 

     int thr_setconcurrency(int new_level);


     int thr_getconcurrency(void);


DESCRIPTION
     These functions are obsolete and maintained for  compatibil-
     ity  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.
