INTRO(3)

NAME
intro - introduction to library routines

DESCRIPTION
This chapter provides information on various library routines.

The SYNOPSIS section of each manual page details the prototype of the routine and any required header files. The DESCRIPTION explains the semantics of the routine.

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.

RETURN VALUES
In this chapter, return types and values are specific to the particular routine. The appropriate manual page should be consulted.

Note that unlike the Chapter 2 calls, routines in this chapter cannot be relied upon to set errno(2) in any predictable way unless doing so is specifically described in the manual page for that routine.
