4 | * Private file definitions for the Common UNIX Printing System (CUPS). | |
5 | * | |
6 | * Since stdio files max out at 256 files on many systems, we have to | |
7 | * write similar functions without this limit. At the same time, using | |
8 | * our own file functions allows us to provide transparent support of | |
9 | * gzip'd print files, PPD files, etc. | |
