mexLock (C and Fortran) - Prevent MEX-file from being cleared from memory

C Syntax

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

Fortran Syntax

mexLock()

Description

By default, MEX-files are unlocked, meaning that a user can clear them at any time. Call mexLock to prohibit a MEX-file from being cleared.

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

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

C Examples

See mexlock.c in the mex subdirectory of the examples directory.
