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, however, the
syntax #include <filename.h> or #include <sys/filename.h> should be used.
Because
the operating system now allows the existence of multiple file system types,
there are several instances of multiple manual pages with the same name.
These pages all display the name of the FSType to which they pertain in
the form name_ fstype at the top of the page. For example, fs_ufs(4)
