KernReadFileAtCache

Synopsis

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

Description

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

Parameters

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. 

Comments

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