NAME

       pthread_setschedprio - dynamic thread scheduling parameters access

SYNOPSIS

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

       int pthread_setschedprio(pthread_t thread, int prio);

       The  pthread_setschedprio()  function  sets the scheduling priority for the thread whose thread ID is given by thread to the value given by
       prio.

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

       If successful, the pthread_setschedprio() function returns 0; otherwise, an error number is returned to indicate the error.

       The pthread_setschedprio() function will fail if:

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

       ENOTSUP	       An attempt was made to set the priority to an unsupported value.

       EPERM	       The caller does not have the appropriate permission to set the scheduling policy of the specified thread.

		       The system does not allow the application to modify the priority to the value specified.

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