- get scheduling parameter limits
cc [ flag... ] file... -lrt [ library... ] #include <sched.h> int sched_get_priority_max(int policy);
int sched_get_priority_min(int policy);
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>.
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 -1 and set errno to indicate the error.
The sched_get_priority_max() and sched_get_priority_min() functions will fail if:
The value of the policy parameter does not represent a defined scheduling policy.
The sched_get_priority_max(), sched_get_priority_min() and sched_rr_get_interval(3RT) functions are not supported by the system.
See attributes(5) for descriptions of the following attributes:

Solaris 2.6 was the first release to support libposix4/librt. Prior to this release, this function always returned -1 and set errno to ENOSYS.
