/prog/ - How does valgrind work?

Name: Anonymous 2010-06-26 14:10

How is valgrind able to replace the malloc functions in programs? I want to do the same thing but with socket functions.

I was hoping for a bit better of an explanation than just code in which I have to read a lot of to fully understand.
