HP C Run-Time Library Reference Manual for OpenVMS Systems

This document is the HP C Run-Time Library (RTL) Reference Manual for OpenVMS Systems, dated January 2005. It serves as a comprehensive reference guide for functions and macros within the HP C RTL across VAX, Alpha, and Intel Itanium processors running OpenVMS.

The manual covers a wide range of programming areas, including:

• Input/Output (I/O) Operations: UNIX, Standard, and Terminal I/O functions.
• Data Manipulation: Character and string handling.
• Mathematical Operations: Various math functions.
• System Interactions: Error and signal handling, subprocess creation, and general system access.
• Screen Management: Curses functions and macros.
• Internationalization: XPG4-compliant internationalization support and date/time functions.

It also highlights portability concerns between operating systems. Notably, socket routines for Internet application programming are not documented here, with users directed to the HP TCP/IP Services for OpenVMS documentation. The manual is intended for both experienced and novice programmers. It specifically applies to OpenVMS I64 Version 8.2 and OpenVMS Alpha Version 8.2.
