mexMakeMemoryPersistent (C and Fortran) - Make memory allocated by MATLAB software persist after MEX-function completes
C Syntax
#include "mex.h"
void mexMakeMemoryPersistent(void *ptr);
Fortran Syntax
mexMakeMemoryPersistent(ptr)
mwPointer 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 software is nonpersistent,
so it is freed automatically when the MEX-function 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 leaks
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. |
