    Command:

    pthread_setconcurrency

    
    
    
    

    SYNOPSIS

           #include <pthread.h>
    
           int pthread_setconcurrency(int new_level);
           int pthread_getconcurrency(void);
    
           Compile and link with -pthread.
    
    
    

    DESCRIPTION

           The pthread_setconcurrency() function informs the implementation of the
           application's  desired  concurrency level, specified in new_level.  The
           implementation takes this only as a hint: POSIX.1 does not specify  the
           level  of  concurrency  that  should be provided as a result of calling
           pthread_setconcurrency().
    
           Specifying new_level as 0 instructs the implementation  to  manage  the
           concurrency level as it deems appropriate.
    
           pthread_getconcurrency()  returns  the current value of the concurrency
           level for this process.
    
    
    

    RETURN VALUE

           On success, pthread_setconcurrency() returns 0; on error, it returns  a
           nonzero error number.
    
           pthread_getconcurrency()  always  succeeds,  returning  the concurrency
           level set by a previous call  to  pthread_setconcurrency(),  or  0,  if
           pthread_setconcurrency() has not previously been called.
    
    
    

    ERRORS

           pthread_setconcurrency() can fail with the following error:
    
           EINVAL new_level is negative.
    
           POSIX.1-2001  also  documents  an EAGAIN error ("the value specified by
           new_level would cause a system resource to be exceeded").
    
    
    

    VERSIONS

           These functions are available in glibc since version 2.1.
    
    
    

    CONFORMING TO

           POSIX.1-2001.
    
    
    

    NOTES

           The default concurrency level is 0.
    
           Concurrency levels are meaningful only for  M:N  threading  implementa-
           tions,  where  at  any moment a subset of a process's set of user-level
           threads may be bound to a smaller number of kernel-scheduling entities.
           Setting the concurrency level allows the application to give the system
           a hint as to the number of kernel-scheduling entities  that  should  be
