CRTL
The complete VSI C Run-Time Library (C RTL) needed for use with
the VSI C compiler is distributed with the OpenVMS operating
system, which runs on Intel[R] Itanium[R] processors.
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 system.
For help on the socket routines used for writing Internet
application programs for the TCP/IP Services protocol, use the
following:
$ HELP TCPIP_Services Programming_Interfaces Sockets_API
Also see the "HP TCP/IP Services for OpenVMS" product
documentation.
