- Anil,
- It contains the AT&T (actually USL or Unix Systems Laboratories) class
- libraries which are shipped with the USL C++ Language System 3.0 (aka
- Cfront 3.0). The libraries are (1) Iostreams
- (2) Complex Numbers
- (3) Tasks
- If you are porting C++ applications from a Unix system, then (1) and (3)
- may be of interest to you. (1) is a type-safe replacement to the ANSI-C
- printf, scanf, etc. family of functions, and it illustrates (both good
- and bad) the effects of multiple inheritance. (2) is useful for Sci/Math
- programmers only, and the class library is a "text-book" example of
- what can be done with OOP. (3) is great on Unix systems, since Unix does
- not have threads, just processes. On OS/2, (3) is less useful than
- using BeginThread/CreateThread etc. (3) is definitely for Unix porters.
- If you are doing stdio-type of programming, then (1) is also useful.
- If you are doing PM programming, it is not.
