FSH_YIELD - Yield processor to higher-priority thread

This function provides the mechanism for relinquishing the processor to 
higher priority threads. 
Calling Sequence   

void far pascal FSH_YIELD(void)

There are no error returns. 
FSDs run under the 2 mS dispatch latency imposed on the OS/2 kernel, 
meaning that no more than 2 mS can be spent in an FSD without an explicit 
block or yield . FSH_YIELD will test to see if another thread is runable 
at the current thread 's priority or at a higher priority. If one exists, 
that thread will be given a chance to run.
