LIB$
LIB$, or the OpenVMS Run-Time Library Facility, is a facility that provides a callable interface to components of OpenVMS operating systems that are difficult to use in a high-level language. LIB$ routines allow access to the following:
- System services
- The command language interpreter (CLI)
- Some VAX machine instructions or the equivalent Alpha instructions
and 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 Compaq DECnet-Plus for OpenVMS full names
- Search for specified files
- Set up and use binary trees
- Signal exceptions
