Preface

This manual provides users of the HP OpenVMS operating system with detailed usage and reference information on library routines supplied in the LIB$ and CVT$ facilities of the Run-Time Library (RTL).

Intended Audience

This manual is intended for system and application programmers who write programs that call LIB$ and CVT$ Run-Time Library routines.

Document Structure

This manual is organized into three parts as follows:

  • The overview chapter provides a brief overview of the LIB$ and CVT$ Run-Time Library facility and lists the LIB$ routines and their functions. It also provides guidelines and information on using the LIB$ facility with VAX and Alpha platforms.
  • The LIB$ reference section describes each library routine contained in the LIB$ Run-Time Library facility. This information is presented using the documentation format described in HP OpenVMS Programming Concepts Manual. Routine descriptions appear alphabetically by routine name.
  • The CVT$ reference section describes the routines contained in the CVT$ Run-Time Library facility. This information is presented using the documentation format described in HP OpenVMS Programming Concepts Manual.

Related Documents

The Run-Time Library (RTL) routines are documented in a series of reference manuals.

General descriptions of OpenVMS RTL routines appear in the following manual:

Conventions

In this manual, every use of DECwindows and DECwindows Motif refers to HP DECwindows Motif for OpenVMS software.

The following conventions are also used in this manual:

Ctrl/ x A sequence such as Ctrl/ x indicates that you must hold down the key labeled Ctrl while you press another key or a pointing device button.
PF1 x A sequence such as PF1 x indicates that you must first press and release the key labeled PF1 and then press and release another key or a pointing device button.
[Return] In examples, a key name enclosed in a box indicates that you press a key on the keyboard. (In text, a key name is not enclosed in a box.)

In the HTML version of this document, this convention appears as brackets, rather than a box.

... A horizontal ellipsis in examples indicates one of the following possibilities:
  • Additional optional arguments in a statement have been omitted.
  • The preceding item or items can be repeated one or more times.
  • Additional parameters, values, or other information can be entered.
.
.
. 		A vertical ellipsis indicates the omission of items from a code example or command format; the items are omitted because they are not important to the topic being discussed.
( ) In command format descriptions, parentheses indicate that you must enclose the options in parentheses if you choose more than one.
[ ] In command format descriptions, brackets indicate optional choices. You can choose one or more items or no items. Do not type the brackets on the command line. However, you must include the brackets in the syntax for OpenVMS directory specifications and for a substring specification in an assignment statement.
| In command format descriptions, vertical bars separate choices within brackets or braces. Within brackets, the choices are optional; within braces, at least one choice is required. Do not type the vertical bars on the command line.
{ } In command format descriptions, braces indicate required choices; you must choose at least one of the options listed. Do not type the braces on the command line.
bold text This typeface represents the introduction of a new term or the name of an argument, an attribute, or a reason.
italic text Italic text indicates important information, complete titles of manuals, or variables. Variables include information that varies in system output (Internal error number), in command lines (/PRODUCER= name), and in command parameters in text (where dd represents the predefined code for the device type).
UPPERCASE TEXT Uppercase text indicates a command, the name of a routine, the name of a file, or the abbreviation for a system privilege.
Monospace text Monospace type indicates code examples and interactive screen displays.

In the C programming language, monospace type in text identifies the following elements: keywords, the names of independently compiled external functions and files, syntax summaries, and references to variables or identifiers introduced in an example.

- A hyphen at the end of a command format description, command line, or code line indicates that the command or statement continues on the following line.
numbers All numbers in text are assumed to be decimal unless otherwise noted. Nondecimal radixes---binary, octal, or hexadecimal---are explicitly indicated.

Part 1
LIB$ Overview Section

 This part contains one chapter that provides a brief overview of the LIB$ and CVT$ Run-Time Library facilities and lists the LIB$ and CVT$ routines and their functions. It also provides guidelines and information on using the LIB$ facility with VAX, Alpha, and HP OpenVMS Industry Standard 64 for Integrity Servers (I64) platforms.

Chapter 1
Overview of the LIB$ Facility

This section describes the OpenVMS Run-Time Library (LIB$) facility and lists the function of each routine within the LIB$ facility.

1.1 Run-Time Library LIB$ Routines

This manual discusses the Run-Time Library (RTL) LIB$ routines that perform general purpose (library) functions. One of the functions of the LIB$ facility is to provide a callable interface to components of OpenVMS operating systems that are difficult to use in a high-level language. LIB$ routines allow access to the following:

  • System services
  • The command language interpreter (CLI)
  • Some VAX machine instructions or the equivalent Alpha or I64 instructions

In addition, LIB$ routines allow you to perform the following operations:

  • Allocate resources that your process needs, such as virtual memory and event flags
  • Convert data types for I/O
  • Enable detection of hardware exceptions (VAX only)
  • Establish condition handlers (VAX only)
  • Generate and display timing statistics while your program is running
  • Get and put strings in the process common storage area
  • Obtain records from devices
  • Obtain the system date and time in various formats
  • Process cross-reference data
  • Process HP DECnet-Plus for OpenVMS full names
  • Search for specified files
  • Set up and use binary trees
  • Signal exceptions

1.1.1 64-Bit Addressing Support (Alpha and I64 Only)

On Alpha and I64 systems, the Run-Time Library (LIB$) routines provide 64-bit virtual addressing capabilities as follows:

  • Most routines now accept 64-bit addresses for arguments passed by reference. Footnotes in the Reference Section of this manual indicate those routines that do not.
  • Most routines also accept either 32-bit or 64-bit descriptors for arguments passed by descriptor. Footnotes in the Reference Section of this manual indicate those routines that do not.
  • In some cases, a new routine was added to support a 64-bit addressing or data capability. These routines carry the same name as the original routine but with a _64 suffix. In general, both versions of the routine support 64-bit addressing, but the routine with the _64 suffix also supports additional 64-bit capability. The 32-bit capabilities of the original routine are unchanged.
  • Specialized routines create and manipulate storage zones in the 64-bit virtual address space. The names of these routines are the same as their 32-bit counterparts but with a _64 suffix. One example is LIB$CREATE_VM_ZONE and LIB$CREATE_VM_ZONE_64. LIB$CREATE_VM_ZONE creates a storage zone in the 32-bit vitual address space, and LIB$CREATE_VM_ZONE_64 creates a storage zone in the 64-bit virtual address space. The function of the original routine is unchanged.

See the HP OpenVMS Programming Concepts Manual for more information about 64-bit virtual addressing capabilities.
