3. Information about the pcre2.x86_64 package on CentOS 7 / RHEL 7

Installed Packages
Name : pcre2
Arch : x86_64
Version : 10.23
Release : 2.el7
Size : 556 k
Repo : installed
From repo : base
Summary : Perl-compatible regular expression library
URL : http://www.pcre.org/
License : BSD
Description : PCRE2 is a re-working of the original PCRE (Perl-compatible
: regular expression) library to provide an entirely new API.
:
: PCRE2 is written in C, and it has its own API. There are three
: sets of functions, one for the 8-bit library, which processes
: strings of bytes, one for the 16-bit library, which processes
: strings of 16-bit values, and one for the 32-bit library, which
: processes strings of 32-bit values. There are no C++ wrappers.
: This package provides support for strings in 8-bit and UTF-8
: encodings. Install pcre2-utf16 or pcre2-utf32 packages for the
: other ones.
:
: The distribution does contain a set of C wrapper functions for the
: 8-bit library that are based on the POSIX regular expression API
: (see the pcre2posix man page). These can be found in a library
: called libpcre2posix. Note that this just provides a POSIX calling
: interface to PCRE2; the regular expressions themselves still
: follow Perl syntax and semantics. The POSIX API is restricted, and
: does not give full access to all of PCRE2's facilities.
