VMS Help  —  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 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

    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
