CRTL
The complete HP C Run-Time Library (C RTL) needed for use with
the HP C compiler is distributed with the OpenVMS operating
system, which runs on VAX, Alpha, and Intel[R] Itanium[R]
processors. HP OpenVMS Industry Standard 64 for Integrity Servers
is the full product name of the OpenVMS operating system on Intel
Itanium processors. The shortened forms, OpenVMS I64 and I64, are
also used throughout this online help.
The C RTL provides routines to perform input/output, character
and string handling, mathematical computations, memory
allocation, error detection, subprocess creation, system access,
and emulation of selected UNIX[R] features. These routines are
provided both in shared image and object module library form.
The C RTL contains XPG4-compliant internationalization support,
providing functions to help you develop software that can run in
different languages and cultures.
This online help describes the C RTL routines available with this
version of the OpenVMS Alpha system.
For help on the socket routines used for writing Internet
application programs for the TCP/IP Services protocol, use the
following:

Also see the "HP TCP/IP Services for OpenVMS" product
documentation.
