    Command:

    pthread_setschedprio

    
    
    

    SYNOPSIS

           #include <pthread.h>
    
           pthread_setschedprio(pthread_t thread, int prio);
    
           Compile and link with -pthread.
    
    
    

    DESCRIPTION

           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 prior-
           ity of a thread.)
    
    
    

    RETURN VALUE

           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

           EINVAL prio is not valid for the scheduling  policy  of  the  specified
                  thread.
    
           EPERM  The caller does not have appropriate privileges to set the spec-
                  ified priority.
    
           ESRCH  No thread with the ID thread could be found.
    
           POSIX.1-2001 also documents an ENOTSUP ("attempt was made  to  set  the
           priority  to an unsupported value") error for pthread_setschedparam(3).
    
    
    

    VERSIONS

           This function is available in glibc since version 2.3.4.
    
    
    

    CONFORMING TO

           POSIX.1-2001.
    
    
    

    NOTES

           For a description of the permissions required to, and  the  effect  of,
           changing  a  thread's scheduling priority, and details of the permitted
           ranges for priorities in each scheduling  policy,  see  sched_setsched-
           uler(2).
