Multiple symbols definition

[Cournapeau David <cournape at atr dot jp>]

Hi, 

	I would like to know where I could find an good explanation about the
way that multiple definitions of one symbol are resolved at link time
and runtime ? My problem is that I would like to control the way that
multiple definition for one symbol are resolved, ie force to resolve the
symbol in one particular library. 

	For example, let's say I want to wrap malloc calls in my dynamic
library, is it possible to link against a small wrapper library which
would define its own malloc, and to force the linker to resolve to this
wrapper library , and not to the C library ?

	Thanks for the help,

	David Cournapeau
