mexMakeMemoryPersistent

Make memory allocated by MATLAB memory allocation routines (mxCalloc, mxMalloc, mxRealloc) persist after the MEX-function completes

C Syntax

• #include "mex.h"
  void mexMakeMemoryPersistent(void *ptr);
  

Arguments

ptr
   Pointer to the beginning of memory allocated by one of the MATLAB memory allocation routines.

Description

By default, memory allocated by MATLAB is nonpersistent, so it is freed automatically when the MEX-file finishes. If you want the memory to persist, you must call mexMakeMemoryPersistent.

Note    If you create persistent memory, you are responsible for freeing it when the MEX-function is cleared. If you do not free the memory, MATLAB will leak memory. To free memory, use mxFree. See mexAtExit to see how to register a function that gets called when the MEX-function is cleared. See mexLock to see how to lock your MEX-function so that it is never cleared.
