    NAME

    
    
    pthread_setschedparam
    
     
    pthread_getschedparam
    
     - thread scheduling parameter manipulation
    
     
    

    LIBRARY

    Lb libpthread
    
     
    

    SYNOPSIS

       #include <pthread.h>
    int pthread_setschedparam (pthread_t thread int policy const struct sched_param *param);
    int pthread_getschedparam (pthread_t thread int *policy struct sched_param *param);
     

    DESCRIPTION

    The pthread_setschedparam ();
    and pthread_getschedparam ();
    functions set and get the scheduling parameters of individual threads. The scheduling policy for a thread can either be SCHED_FIFO (first in, first out), SCHED_RR (round-robin), or SCHED_OTHER (timesharing). Valid thread priorities (accessed via param->sched_priority must be within the range returned by the sched_get_priority_min2 and sched_get_priority_max2 system calls.  

    RETURN VALUES

    If successful, these functions return 0. Otherwise, an error number is returned to indicate the error.  

    ERRORS

    The pthread_setschedparam ();
    function will fail if:

    Bq Er EINVAL
    Invalid value for Fa policy .
    Bq Er ENOTSUP
    Invalid value for scheduling parameters.
    Bq Er ESRCH
    Non-existent thread Fa thread .

    The pthread_getschedparam ();
    function will fail if:

    Bq Er ESRCH
    Non-existent thread Fa thread .

     

    SEE ALSO

    and pthread_getschedparam ();
    functions conform to St -susv2 .
