thr_getprio(3C) 					   Standard C Library Functions 					   thr_getprio(3C)

NAME
       thr_getprio, thr_setprio - access dynamic thread scheduling

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

       int thr_setprio(thread_t target_thread, int priority);

       int thr_getprio(thread_t target_thread, int *priority);

DESCRIPTION
       The  thr_setprio()  function sets the scheduling priority for the thread specified by target_thread within the current process to the value
       given by priority.

       The thr_getprio() function stores the current priority for the thread specified by target_thread in the location pointed to by priority.

       If the thr_setprio() function fails, the scheduling priority of the target thread is not changed.

       See priocntl(2), pthread_setschedprio(3C), and sched_setparam(3C).

RETURN VALUES
       If successful, the thr_getprio() and thr_setprio() functions return 0. Otherwise, an error number is returned to indicate the error.

ERRORS
       The thr_getprio() and thr_setprio() functions will fail if:

       ESRCH	The value specified by target_thread does not refer to an existing thread.

       The  thr_setprio() function will fail if:

       EINVAL	 The value of priority is invalid for the scheduling policy of the specified thread.

       EPERM	 The caller does not have the appropriate permission to set the priority to the value specified.
