Using C, I'm trying to find the location and number of matches of a substring within another parent string. Because I also need to include approximate (hamming distance) matches, I'm using the tre library found here: http://laurikari.net/tre/.
I'm having trouble understanding some of the documentation on the site, likely because I'm not too familiar with regex lingo. According to the tre documentation, I can get more specific information about 'submatches'. Are these the matches I'm looking for?
Thanks!
