mwSetLibraryAllocFcns
0mwSetLibraryAllocFcns
Purpose Set memory management functions for MATLAB C++ Math Library
C++ Prototype void mwSetLibraryAllocFcns(
mwMemCallocFunc callocProc,
mwMemFreeFunc freeProc,
mwMemReallocFunc reallocProc,
mwMemAllocFunc mallocproc,
mwMemCompactFunc=0);
Arguments callocProc
A pointer to a function that allocates memory. mwMemCallocFunc is defined as:
typedef void *(*mwMemCallocFunc)(size_t, size_t);
freeProc
A pointer to a function that frees memory. mwMemFreeFunc is defined as:
typedef void (*mwMemFreeFunc)(void *);
reallocProc
A pointer to a function that reallocates memory. mwMemReallocFunc is defined
as:
typedef void *(*mwMemReallocFunc)(void *, size_t);
mallocproc
A pointer to a function that allocates memory. mwMemAllocFunc is defined as:
typedef void *(*mwMemAllocFunc)(size_t);
compactproc
Not currently used.
Description Sets the MATLAB C++ Math Library’s memory management functions. Gives
you complete control over memory management.
To set up your own memory management routines, you need to write four
routines: two memory allocation routines, one memory reallocation routine,
and one deallocation routine. You then call mwSetLibraryAllocFcns() to
register those routines with the library.
You cannot omit any of the four routines. However, the last argument to
mwSetLibraryAllocFcns(), mwMemCompactFunc, is not currently used and is
