DESCRIPTION
This section describes functions found in various libraries, other than
those functions that directly invoke HP-UX system primitives, which are
described in Section (2) of this volume. Certain major collections are
identified by a letter after the section identifier (3):
(3C) These functions, together with the Operating System
Calls and those marked (3S), constitute the Standard C
Library, which is automatically loaded by the C com‐
piler, cc(1). Declarations for some of these func‐
tions can be obtained from files indicated in the
appropriate entries.
(3E) These functions constitute the ELF access library
which lets a program manipulate ELF (Executable and
Linking Format) object files, archive files, and ar‐
chive members. The link editor searches this library
if the option is specified. The header file provides
type and function declarations for all library ser‐
vices (described in elf(3E).
(3G) These functions constitute the graphics library and
are documented in separate manuals.
(3I) These functions constitute the instrument support
(Device I/O) library.
(3M) These functions constitute the Math Library, The link
editor searches this library if the option is speci‐
fied. Declarations for these functions are available
in the header files and Several generally useful math‐
ematical constants are also defined in (see math(5)).
(3N) These functions are applicable to the Internet network
and are part of the standard C library,
(3S) These functions constitute the ``standard I/O pack‐
age'' (see stdio(3S)). These functions are in the
library already mentioned. Declarations for these
functions can be obtained from the file
(3T) These functions constitute the Pthreads Library. The
link editor (see ld(1)) searches this library if the
option is specified. See pthread(3T) for more
detailed information on threads.
(3X) Various specialized libraries. The files in which
these libraries are found are specified in the appro‐
priate entries.
DIAGNOSTICS
Functions in the C and Math Libraries, (3C) and (3M), may return the
conventional values or when the function is undefined for the given
arguments or when the value is not representable. is defined as in the
header file. Functions in the Math Library may also return or a In
these cases, the external variable (see errno(2)) may also be set to
the value [EDOM] or [ERANGE].
