FsRtlIncrementCcFastReadNoWait function (ntifs.h)

The FsRtlIncrementCcFastReadNoWait routine increments the CcFastReadNoWait performance counter in a per processor control block of cache manager system counters.

Syntax

void FsRtlIncrementCcFastReadNoWait();

Return value

None

Remarks

FsRtlIncrementCcFastReadNoWait increments the CcFastReadNoWait performance counter in the per processor control block of cache manager system counters. This counter indicates that a fast I/O read operation, FsRtlCopyRead, was called with the Wait parameter set to FALSE indicating that the caller cannot be put into a wait state until all the data has been copied.

File system drivers should call this function to update the performance counter if the driver chooses to override the default fast I/O read handler.
