ajsmcre.
Results Interrupts are disabled and then restored to their state at the time of the
call.
Status is returned.
AEROK = Call successful
AERNSS = Invalid semaphore id
AERRNY = Resource semaphore cannot be released since the calling
task does not own the resource.
Note The resource's use count is immediately set to zero and the resource freed.
The resource will immediately be given to the task (if any) which is
waiting at the head of the resource semaphore wait queue. Task
rescheduling occurs immediately if necessary.
Restriction You must not attempt to free a counting semaphore. Use ajsmsig for that
purpose.
