thr_getconcurrency, thr_setconcurrency - get or set thread concurrency level

cc -mt [ flag... ] file...[ library... ]
#include <thread.h>

int thr_setconcurrency(int new_level);

int thr_getconcurrency(void);

These functions are obsolete and maintained for compatibility 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.

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.

The thr_setconcurrency() function will fail if: EAGAIN

EINVAL
