PTHREAD_SETSCHEDPRIO(3)   Linux Programmer's Manual  PTHREAD_SETSCHEDPRIO(3)

NAME         top

       pthread_setschedprio - set scheduling priority of a thread

SYNOPSIS         top

       #include <pthread.h>

       int pthread_setschedprio(pthread_t thread, int prio);

       Compile and link with -pthread.

DESCRIPTION         top

       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.)

RETURN VALUE         top

       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.

ERRORS         top

       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).

VERSIONS         top

       This function is available in glibc since version 2.3.4.
