I have this huge buffer (size of an uncompressed image file), and I've had two scenarios so far: 1. Reading in the file off disk into memory using fscanf. Works great, since each successive read of fscanf increments the file pointer. 2. Reading in the file from a raw memory space using sscanf (it was downloaded internally via FTP)... Doesn't work, because apparently, sscanf has no way of returning a pointer to where it last scanned... so it starts at the beginning of the buffer for each successive scan. Can anyone think of a way to get a pointer of where sscanf last scanned? Is there another function that can do this? It's awfully tough to manually calculate it, since the data scanned in is not in char form. Maybe there's a way to get my app to *think* it's a file stream, so I can use fscanf? Thanks for any suggestions! [edited by - Riskbreaker on March 7, 2003 3:12:18 PM]

Rather than trying to cram the entire buffer into sscanf at once, peel off smaller chunks and feed it those instead.

String tokenizer! duh... thanks

RTFM (looking for %n)

What exactly are you reading?
