I don't understand.  Suppose that I want to substitute my strlen() logic
for the vendors implementation of strlen() in such a way that not only
my source's calls on strlen() are affected, but also any 3rd party's
library's uses of strlen() get the "benefit".   How does your technique
apply to that scenario?
