VOID
VC_Stall(
int nMicrosecs
);
The VC_Stall function stalls the current processor for the specified number of microseconds.
None.
The VC_Stall function causes the current processor to execute a processor-specific wait loop until the specified time has passed. The function is useful for pausing between device access operations, if there is a potential for fast processors to send instructions to the device at a speed that is too high for the device.
Delays longer than 25 microseconds are not recommended.
Your driver can call VC_Install when executing at any IRQL.
