Macro Definition Documentation

#define __STDC_FORMAT_MACROS

This file is part of the CernVM File System.

An optimized virtual file system layer for the client only. It expects to operate on immutable, valid SQlite files. Hence it can do a few optimizations. Most notably it doesn't need to know about the path of the SQlite file once opened. It works purely on the file descriptor.
