The entire regular expression's match addresses are stored in pmatch[0]. (Note that to return the offsets of N subexpression matches, nmatch must be at least N+1.) Any unused structure elements will contain the value -1. The regmatch_t structure which is the type of pmatch is defined in .

Regexp golf. Code golf is a term used for the game of trying to express a particular program in as few characters as possible. Similarly, regexp golf is the practice of writing as tiny a regular expression as possible to match a given pattern, and only that pattern.

A RegEx, or Regular Expression, is a sequence of characters that forms a search pattern. RegEx can be used to check if a string contains the specified search pattern.

Learn more about: In this article. Defines a class template to parse Regular Expressions (C++), and several class templates and functions to search text for matches to a regular expression object. Regular expressions (shortened as "regex") are special strings representing a pattern to be matched in a search operation. They are an important tool in a wide variety of computing applications, from programming languages like Java and Perl, to text processing tools like grep, sed, and the text editor vim.
