sched_get_priority_max(3)				     Library Functions Manual					 sched_get_priority_max(3)

NAME

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

LIBRARY

       Realtime Library (librt.so, librt.a)

SYNOPSIS

       #include <sched.h>

       int sched_get_priority_max (
       int policy);

       int sched_get_priority_min (
       int policy);

PARAMETERS

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

DESCRIPTION

       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

       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

       The sched_get_priority_max and sched_get_priority_min functions fail under the following condition:

       [EINVAL]       The value of the policy argument does not represent a defined scheduling policy.

NAME

       sched_get_priority_max, sched_get_priority_min - get scheduling parameter limits

SYNOPSIS

       #include <sched.h>

       int sched_get_priority_max(int policy);

       int sched_get_priority_min(int policy);

DESCRIPTION

       The sched_get_priority_max() and sched_get_priority_min() functions return the appropriate maximum or minimum, respectfully, for the sched-
       uling policy specified by policy.

       The value of policy is one of the scheduling policy values defined in <sched.h>.

RETURN VALUES

       If successful, the sched_get_priority_max() and sched_get_priority_min() functions return the appropriate maximum or minimum priority  val-
       ues, respectively. If unsuccessful, they return -1 and set errno to indicate the error.

ERRORS

       The  sched_get_priority_max() and sched_get_priority_min() functions will fail if:
