FsRtlIncrementCcFastReadNoWait routine

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

Syntax

  VOID 
);

Parameters

None

Return value

This routine does not return a value.

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.

Requirements

Version

This routine is available on Microsoft Windows XP and later.
