mexIsLocked (C and Fortran)

Determine if MEX-file is locked

C Syntax

#include "mex.h"
bool mexIsLocked(void);

Fortran Syntax

#include "fintrf.h"
integer*4 mexIsLocked()


Logical 1 (true) if the MEX-file is locked; logical 0 (false) if the file is unlocked.


Call mexIsLocked to determine if the MEX-file is locked. By default, MEX-files are unlocked, meaning you can clear the MEX-file at any time.

To unlock a MEX-file, call mexUnlock.
