NAME

sched_get_priority_max, sched_get_priority_min - get priority limits (REALTIME)

 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 scheduling policy specified by policy.

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

 RETURN VALUE

If successful, the sched_get_priority_max() and sched_get_priority_min() functions return the appropriate maximum or minimum values, respectively. If unsuccessful, they return a value of -1 and set errno to indicate the error.

 ERRORS

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

[EINVAL]

The value of the policy parameter does not represent a defined scheduling policy.

[ENOSYS]

The sched_get_priority_max(), sched_get_priority_min() and sched_rr_get_interval() functions are not supported by this implementation.

 EXAMPLES

None.

 APPLICATION USAGE

None.

 FUTURE DIRECTIONS

None.
