Lock a MEX-file so that it cannot be cleared from memory

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

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, call mexUnlock.

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