     int                         *prioceiling);

Parameters

attr

(IN) Points to the mutex attribute object.

prioceiling

(OUT) Points to the value for the prioceiling attribute.

Remarks

The prioceiling attribute contains the priority ceiling of initialized mutexes. On NetWare, this attribute can be set, but it currently has no effect on the behavior of the mutex.
