Is there a way to redefine malloc at link time on Windows?

Question

I would like to replace the default malloc at link time to use a custom malloc. But when I try to redefine malloc in my program, I get this error:

MSVCRT.lib         


        

Answer 1

What about defining malloc=_custom_malloc in the project makefile. Than adding a file such as:

my_memory.c
#undef malloc
#undef calloc
...
void *_custom_malloc(int size) { return jmalloc(size); }
void *_custom_calloc(int size) { return jcalloc(size); }
...
