NAME
       intro - introduction to subroutines and libraries

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 compiler, cc(1).  Declarations for some of these functions 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 archive members.  The link editor searches this library if the option is specified.  The
			header file provides type and function declarations for all library services (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  specified.   Declara-
			tions  for  these functions are available in the header files and Several generally useful mathematical 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 package'' (see stdio(3S)).  These functions are in the library already  men-
			tioned.  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 spec-
			ified.	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 appropriate 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].

FILES

       (For PA-RISC systems.)		  SVID3, XPG4.2, and ANSI C compliant math archive library.
