pthread_setconcurrency(int new_level); int
pthread_getconcurrency(void); Compile and link with -pthread.
DESCRIPTIONThe pthread_setconcurrency() function informs the
implementation of the application's desired concurrency level,
specified in new_level. The implementation only takes this 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. RETURN VALUEOn success, pthread_setconcurrency()
returns 0; on error, it returns a nonzero error number.
ERRORSpthread_setconcurrency() can fail with the following
error: - new_level is negative. VERSIONSThese functions are
available in glibc since version 2.1. NOTESThe default
concurrency level is 0. Concurrency levels are onl
