String Length

by AdamStanislav - uploaded on August 1, 2016, 11:47 pm

Assembly language code to find the length of a NUL-terminated string, which I posted on http://www.int80h.org/strlen/ (one of my many web sites) back in 2000, now turned into an SVG graphic. It expects ES:EDI/RDI to point at the start of the string. At the end, the length of the string, not counting the terminating NUL, is in ECX.
