mexMakeMemoryPersistent

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

Fortran Syntax

• subroutine mexMakeMemoryPersistent(ptr)
  integer*4 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-file is cleared. If you do not free the memory, MATLAB will leak memory. To free memory, use mxFree. See mexAtExit on how to register a function that gets called when the MEX-file is cleared. See mexLock on how to lock your MEX-file so that it is never cleared.
