Intro, intro - introduction to file formats
This section outlines the formats of various files. The C
structure declarations for the file formats are given where
applicable. Usually, the headers containing these structure
declarations can be found in the directories /usr/include or
/usr/include/sys. For inclusion in C language programs, how-
ever, the syntax #include <filename.h> or #include
<sys/filename.h> should be used.
