This call releases ownership of a Fast-Safe (FS) RAM semaphore.
DosFSRamSemClear
FSRamSemStructure (PDOSFSRSEM) - input
DosFSRamSemClear decrements fs_UseCount, which is incremented by DosFSRamSemRequest. Recursive requests for FS RAM semaphores are supported by this use count, which keeps track of the number of times the owner has issued a DosFSRamSemRequest without a corresponding DosFSRamSemClear. If the call to DosFSRamSemClear decrements the use count to zero, the semaphore is set unowned, and any threads that were blocked waiting for the semaphore resume execution.
DosFSRamSemClear cannot be issued against a FS RAM semaphore that is owned by another thread.
