.TH INTRO 3 "2 February 1997" GNO "Library Routines"
.SH NAME
.BR intro
\- introduction to library routines
.SH DESCRIPTION
This chapter provides information on various library routines.
.LP
The
.BR SYNOPSIS
section of each manual page details the prototype of the routine
and any required header files.  The 
.BR DESCRIPTION
explains the semantics of the routine.
.LP
Reference may be made to symbolic links or other features
or functions that are either unimplemented or otherwise unavailable
under GNO.  This information has often been obtained from the original
BSD manual pages.  In most cases such information has been retained
in the GNO manual pages either because such functionality is planned
or because the information is relevent to code intended to run on 
other BSD operating systems.
.SH RETURN VALUES
In this chapter, return types and values are specific to the particular
routine.  The appropriate manual page should be consulted.
.LP
Note that unlike the Chapter 2 calls, routines in this chapter cannot
be relied upon to set
.BR errno (2)
in any predictable way unless doing so is specifically described in
the manual page for that routine.
