Topics
POSIX Confidence: 92% Arrow up

The Portable Operating System Interface (POSIX) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems.

POSIX defines the application programming interface (API), along with command line shells and utility interfaces, for software compatibility with variants of Unix and other operating systems.

Perl Compatible Regular Expressions Confidence: 90% Arrow up

Perl Compatible Regular Expressions (PCRE) is a regular expression C library inspired by the regular expression capabilities in the Perl programming language.

Philip Hazel started writing PCRE in summer 1997.

PCRE's syntax is much more powerful and flexible than either of the POSIX regular expression flavors and than that of many other regular-expression libraries.

Pattern matching Confidence: 86% Arrow up

In computer science, pattern matching is the act of checking a given sequence of tokens for the presence of the constituents of some pattern.

In contrast to pattern recognition, the match usually has to be exact.

The patterns generally have the form of either sequences or tree structures.

Uses of pattern matching include outputting the locations (if any) of a pattern within a token sequence, to output some component of the matched pattern, and to substitute the matching pattern with some other token sequence (i.e., search and replace).

Perl Confidence: 83% Arrow up

Perl is a family of high-level, general-purpose, interpreted, dynamic programming languages.

The languages in this family include Perl 5 and Perl 6.

Native API Confidence: 81% Arrow up

The Native API (with capitalized N) is a lightweight application programming interface (API) used by Windows NT and user mode applications.

This API is used in the early stages of Windows NT startup process, when other components and APIs are still unavailable.

Therefore, a few Windows components, such as the Client/Server Runtime Subsystem (CSRSS), are implemented using the Native API.

The Native API is also used by subroutines such as those in kernel32.dll that implement the Windows API, the API based on which most of the Windows components are created.
