|
The PCRE library is a set of functions that implement regular
|
|
expression pattern matching using the same syntax and semantics as
|
|
Perl 5. PCRE has its own native API, as well as a set of wrapper
|
|
functions that correspond to the POSIX regular expression API. The
|
|
PCRE library is free, even for building proprietary software.
