Make memory allocated by MATLAB® software persist after MEX-function completes
#include "mex.h" void mexMakeMemoryPersistent(void *ptr);
mexMakeMemoryPersistent(ptr) mwPointer ptr
Pointer to the beginning of memory allocated by one of the MATLAB memory allocation routines
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. |
