mexLock (C and Fortran)

Prevent clearing MEX file from memory

C Syntax

#include "mex.h"
void mexLock(void);

Fortran Syntax

#include "fintrf.h"
subroutine mexLock()


By default, MEX files are unlocked, meaning you can clear them at any time. Call mexLock to prohibit clearing a MEX file.

To unlock a MEX file, call mexUnlock. Do not use the munlock function.

mexLock increments a lock count. If you call mexLock n times, call mexUnlock n times to unlock your MEX file.
