VHLockMem - Syntax

Description: 

VHLockMem makes code or data segments available for ring 0 interrupt-time 
processing. At interrupt time, code and data segments must be 
non-swappable and accessible from the ring 0 context. 

#include <GRADD.h>

PVOID    pAddress;  /*  Address within the first page of code or data. */
ULONG    ulLength;  /*  Size of code or data segment. */
BOOL     fData;     /*  FALSE indicates code segment; TRUE indicates data segment. */
ULONG    rc;        /*  Return value. */

rc = VHLockMem(pAddress, ulLength, fData);
