FsRtlIncrementCcFastReadResourceMiss function (ntifs.h)
The FsRtlIncrementCcFastReadResourceMiss routine increments the CcFastReadNotPossible performance counter in a per processor control block of cache manager system counters.
Syntax
void FsRtlIncrementCcFastReadResourceMiss();
Return value
None
Remarks
FsRtlIncrementCcFastReadResourceMiss increments the CcFastReadReadResourceMiss 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, but fast I/O was not possible because the file resource could not be acquired for shared access.
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.
