ot, a programming question

[Gregory Nowak]

Hi all,

There is something that's been eating away at my cariousity for the last few days, and I just had to ask the below.
Say you run a program such as mpg123 or any other program which minipulates files, and you pass it *.*, or my?.mp3 to open. How does it parce that to get a list of files that match *.* or my?.mp3? I tried looking for mpg123 code that does that, but couldn't find it.
Could someone please enlighten me, I'm very much interested. Thanks.
Greg
