mexMakeMemoryPersistent (C and Fortran)
Make memory allocated by MATLAB persist after MEX function completes
C Syntax
#include "mex.h" void mexMakeMemoryPersistent(void *ptr);
Fortran Syntax
#include "fintrf.h" subroutine mexMakeMemoryPersistent(ptr) mwPointer ptr
Description
By default, memory allocated by MATLAB® is nonpersistent,
so it is freed automatically when the MEX function finishes. If you
want the memory to persist, 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.
