RtLockProcess

RtLockProcess locks certain sections of a process' virtual address space into physical memory.

Syntax

BOOL RtLockProcess(
    ULONG Section
);

Parameters

Section

A number specifying which sections to lock. Currently, RT_PLOCK_ALL is supported. This locks down all pageable process sections.

Return Values

TRUE if the function succeeds, FALSE if invalid parameters are specified

Remarks

RtLockProcess locks down all specified eligible committed memory sections of the process, so that they are not paged out, and so that no page faults occur during execution.

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

Since all RTSS processes are always locked, this function has no effect in the RTSS environment.

Requirements

Header	Rtapi.h
Library	rtapi_w32.lib (Windows), Rtx_Rtss.lib (RTSS)
