NAME
intro - introduction to file formats
DESCRIPTION
This section outlines the formats of various files. The C structure
declarations for the file formats are given where applicable.
Usually, the header files 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.
Some of the AT&T 3B2 SVR4 documentation set guides include duplicates
of relevant manpages. In this documentation set, all manpages may be
found in the appropriate Reference Manual and, with the exception of
the Programmer's Guide: XWIN Graphical Windowing System and the
Programmer's Guide: OPEN LOOK Graphical User Interface, are never
duplicated in the guides.
The Reference Manual pages are divided as follows: User's Reference
Manual: Section 1 and all subsections (except 1M). System
Administrator's Reference Manual: Sections 1M, 7 and 8. Programmer's
Reference Manual: Section 2 through 6.
Because the UNIX 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 centered and in parentheses at the
top of the page.
