pthread_setschedprio(3) Library Functions Manual pthread_setschedprio(3)

ИМЯ

       pthread_setschedprio - set scheduling priority of a thread

БИБЛИОТЕКА

       POSIX threads library (libpthread, -lpthread)

СИНТАКСИС

       #include <pthread.h>

       int pthread_setschedprio(pthread_t thread, int prio);

ОПИСАНИЕ

       The pthread_setschedprio() function sets the scheduling priority
       of the thread thread to the value specified in prio.  (By
       contrast pthread_setschedparam(3) changes both the scheduling
       policy and priority of a thread.)

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       On success, this function returns 0; on error, it returns a
       nonzero error number.  If pthread_setschedprio() fails, the
       scheduling priority of thread is not changed.

ОШИБКИ

       EINVAL prio is not valid for the scheduling policy of the
              specified thread.

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

       ESRCH  No thread with the ID thread could be found.

       POSIX.1 also documents an ENOTSUP ("attempt was made to set the
       priority to an unsupported value") error for
       pthread_setschedparam(3).
