UNIX Performance Products: T-ISAM

• A library of C-callable routines to create and access T-ISAM files. These routines are a super-set of the C-ISAM library functions.

• Include files (to be included in C language programs that refer to the T-ISAM archive library).

• Utilities for manipulating T-ISAM files.

• Variable-length record support with optional same-character compression for better disk utilization.

• Data and index information that can be kept in the same file or in different files. If different files are used, they can be kept on different disks for better performance.

• Selectable protection against process or system aborts in the midst of T-ISAM file accesses.

• Support for a variety of file and record-locking capabilities.

• Keys that consist of up to 8 noncontiguous segments of the record. Each segment may consist of 1-byte characters, 2-byte integers, 4-byte integers, 4-byte floating-point numbers, or 8-byte floating-point numbers. Each segment may be ordered ascending or descending.

• Customizing capability.

• Capability of the same process to open the same T-ISAM file multiple times for multiple currencies.
