[Coding style question] XXX_register or register_XXX

[Rusty Lynch]

Is there an accepted standard on naming for registration functions?  If have
a foo
object that other things can register and unregister with, should the
function names be:

int register_foo(&something);
int unregister_foo(&something);

 - or -

int foo_register(&something);
int foo_unregister(&something);
