NAME    [Toc]    [Back]

       pthread_getconcurrency  - Obtains the value of the concurrency
 level global variable for this process

SYNOPSIS    [Toc]    [Back]

       #include <pthread.h>

       int pthread_getconcurrency(
               void );

LIBRARY    [Toc]    [Back]

       DECthreads POSIX 1003.1c Library (libpthread.so)

STANDARDS    [Toc]    [Back]

       Interfaces documented on this reference  page  conform  to

       None

DESCRIPTION    [Toc]    [Back]

       This routine obtains and returns the value of the "concurrency
  level" global setting for the calling thread's process.
 Because DECthreads automatically manages the concurrency
  of  all  threads  in  a multithreaded process, DECthreads
 ignores this concurrency level value.

       The concurrency level value has no effect on the  behavior
       of a multithreaded program that uses DECthreads. This routine
 is provided for Single UNIX Specification, Version 2,
       source  code  compatibility  and  has no other effect when
       called.

       The initial concurrency level is zero (0), indicating that
       DECthreads controls the concurrency level.

       The concurrency level can be set using the pthread_setconcurrency(3) routine.

RETURN VALUES    [Toc]    [Back]

       This routine always returns the value  of  this  process's
       concurrency  level  global  variable.  If this process has
       never called the pthread_setconcurrency(3)  routine,  this
       routine returns zero (0).

ERRORS    [Toc]    [Back]

       None
