A Portable C++ Regular Expression Facility - Regex(3C++)

A Portable C++ Regular Expression Facility - Regex(3C++)

Regular expressions are a well-known and widely-used programming device. They are ubiquitous in the shell (ls *.c), part of the interface of many programs egrep(1), sed(1), awk(1), ...), and useful in solving many programming problems (for example, lexing source text). Unfortunately, the regular expression routines provided in the standard C library differ in functionality and interface from machine to machine, making it difficult to write portable code. In this paper, we present yet another regular expression library. This library provides the C++ programmer with a useful, pleasant, and consistent set of functionality. The library is completely self-contained, making it possible for C++ programmers to write portable code using regular expressions.
