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

LIBRARY
       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS
       #include <pthread.h>

       int pthread_getconcurrency(
			  void);

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

       IEEE Std 1003.1c-1995, POSIX System Application Program Interface

PARAMETERS
       None

DESCRIPTION
       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
       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
       None
