I have the following question:

Does Microsoft Visual Studio (I’m using 2008 SP1) offer any way to override standart C functions such as malloc, memcpy?

Suppose I have some externally built library, which contains malloc.obj and memcpy.obj.
Library is called library.lib.

How should I build my project so that the compiler uses my (overriden) versions of malloc() and memcpy() routines instead of those provided (I assume they share the same syntax)?

The point of whole this thing is about changing every malloc in my project without making name aliases like my_malloc or similiar, so that I could compare performance.

Is this possible?

Thank you.

    Have not tried this but – in Project properties -> Linker -> Input, set ‘Ignore All Default Libraries’ to Yes. Then set ‘Additional Dependencies’ = library.lib;libcmt.lib.

    This ought to include your library ahead of the standard static CRT. Provided function linkage is the same in each this should do what you want. Though how malloc/free are linked to the OS in the two static libs may be problematic. I assume library.lib also redefines realloc/free/calloc etc?
