This manual provides users of the OpenVMS operating system with detailed usage and reference information about the string manipulation routines supplied in the STR$ facility of the Run-Time Library.
This manual is intended for system and application programmers who write programs that call STR$ Run-Time Library routines.
This manual is organized into two parts as follows:
The Run-Time Library routines are documented in a series of reference manuals. A description of how the Run-Time Library routines are accessed and of the OpenVMS features and functionality available through calls to the STR$ Run-Time Library appear in the OpenVMS Programming Concepts Manual. Descriptions of other RTL facilities and their corresponding routines and usages are discussed in the following books:
The Guide to the POSIX Threads Library contains guidelines and reference information for Compaq POSIX Threads2, the Compaq Multithreading Run-Time Library.
The OpenVMS Calling Standard contains useful information for anyone who needs to call Run-Time Library routines.
Application programmers using any programming language can refer to the Guide to Creating OpenVMS Modular Procedures for writing modular and reentrant code.
High-level language programmers will find additional information on calling Run-Time Library routines in their language reference manual. Additional information may also be found in the language user's guide provided with your OpenVMS language software.
For a complete list and description of the manuals in the OpenVMS documentation set, see the OpenVMS Version 7.3 New Features and Documentation Overview.
