RtLockKernel

RtLockKernel locks certain sections of a Windows kernel's virtual address space into physical memory.

Syntax

BOOL RtLockKernel(
    ULONG Section
);

Parameters

Section

A number specifying which section of the kernel to lock. Currently, RT_KLOCK_ALL is supported. This will lock down all pageable kernel sections.

Return Values

TRUE if the function completes successfully, FALSE if invalid parameters are specified

Remarks

RtLockKernel locks down all specified eligible sections of the kernel's memory, so that it is not paged out, and so that it does not incur page faults during execution.

IMPORTANT! Using this function can have a significant negative impact on system performance.

Since all RTSS and Windows kernel portions of memory used by RTSS are always locked, this function has no impact on RTSS determinism. This call has no effect when issued from RTSS applications.

Requirements

Header	Rtapi.h
Library	Rtx_Rtss.lib
