NAME    [Toc]    [Back]

       sched_get_priority_max,  sched_get_priority_min  - Returns
       the maximum or minimum priority for the specified scheduling
 policy (P1003.1b)

SYNOPSIS    [Toc]    [Back]

       #include <sched.h>

       int sched_get_priority_max ( int policy);

       int sched_get_priority_min ( int policy);


LIBRARY    [Toc]    [Back]

       Realtime Library (librt.so, librt.a)

PARAMETERS    [Toc]    [Back]

       Specifies  one  of  the  scheduling policies as defined in
       <sched.h>.

DESCRIPTION    [Toc]    [Back]

       The  sched_get_priority_max   and   sched_get_priority_min
       functions  return  the maximum or minimum priority for the
       specified scheduling policy. The value of the policy argument
  must  be one of the scheduling policies (SCHED_FIFO,
       SCHED_RR, or SCHED_OTHER), as defined in <sched.h>.

       No special privileges are needed to use the sched_get_priority_max
 and sched_get_priority_min functions.

RETURN VALUES    [Toc]    [Back]

       On  a successful call, the requested value is returned. If
       a call fails to complete successfully, a value  of  -1  is
       returned, and errno is set to indicate the error.

ERRORS    [Toc]    [Back]

       The   sched_get_priority_max   and  sched_get_priority_min
       functions fail under the following condition: The value of
       the  policy argument does not represent a defined scheduling
 policy.
