mexLock

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

C Syntax

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

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, call mexUnlock.

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

Examples

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