Where is the implementation of strlen() in GCC?

Question

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

Answer 1

Here's the bsd implementation

size_t
strlen(const char *str)
{
        const char *s;

        for (s = str; *s; ++s)
                ;
        return (s - str);
}
