Can anyone point me to the definition of strlen() in GCC? I\'ve been grepping release 4.4.2 for about a half hour now (while Googling like crazy) and I can\'t seem
Google Code Search is a good starting point for questions like that. They usually point to various different sources and implementations of a function.
In your particular case: GoogleCodeSearch(strlen)
Google Code Search was completely shut down on March 2013
