KernReadFileAtCache

Synopsis

APIRET APIENTRY KernReadFileAtCache(KEEhfile khfd,KEECachePages** ptr, QWORD off, ULONG nbytes, PULONG nread);

This seems to do the same as KernReadAtFile, but reads from the cache and returns the corresponding pages of the cache data structure.

khfd

   SFT pointer

ptr

   Pointer to a variable the receives the cache data structure for the specified data blocks.

off

   Offset in file to start reading

nbytes

   Number of bytes to read

nread

   Pointer to an ULONG to receive the number of bytes actually read.

Yet another JFS hack. Meanwhile I understand why IBM is reluctant to provide JFS support for Warp 4.
