I am completely new to perl programming. My father is helping me learn said programming language. However, I am stuck on one of the assignments he has given me, and I can't find very much help with it via google, either because I have a tiny attention span, or because I can be very very dense.

PCRE_COMPILE2(3) Library Functions Manual PCRE_COMPILE2(3)
NAME
PCRE - Perl-compatible regular expressions
SYNOPSIS
#include <pcre.h>
pcre *pcre_compile2(const char *pattern, int options,
int *errorcodeptr,
const char **errptr, int *erroffset,
const unsigned char *tableptr);
DESCRIPTION
This function compiles a regular expression into an internal form. It is the same as pcre_compile(), except for the addition of the error-
codeptr argument. The arguments are:
pattern A zero-terminated string containing the
regular expression to be compiled
options Zero or more option bits
errorcodeptr Where to put an error code
errptr Where to put an error message
erroffset Offset in pattern where error was found
tableptr Pointer to character tables, or NULL to
use the built-in default
The option bits are:
PCRE_ANCHORED Force pattern anchoring
PCRE_AUTO_CALLOUT Compile automatic callouts
PCRE_CASELESS Do caseless matching
PCRE_DOLLAR_ENDONLY $ not to match newline at end
PCRE_DOTALL . matches anything including NL
PCRE_DUPNAMES Allow duplicate names for subpatterns
PCRE_EXTENDED Ignore whitespace and # comments
PCRE_EXTRA PCRE extra features
(not much use currently)
PCRE_FIRSTLINE Force matching to be before newline
PCRE_MULTILINE ^ and $ match newlines within data
PCRE_NEWLINE_ANY Recognize any Unicode newline sequence
PCRE_NEWLINE_ANYCRLF Recognize CR, LF, and CRLF as newline sequences
PCRE_NEWLINE_CR Set CR as the newline sequence
PCRE_NEWLINE_CRLF Set CRLF as the newline sequence
PCRE_NEWLINE_LF Set LF as the newline sequence
PCRE_NO_AUTO_CAPTURE Disable numbered capturing paren-
theses (named ones available)
PCRE_UNGREEDY Invert greediness of quantifiers
PCRE_UTF8 Run in UTF-8 mode
PCRE_NO_UTF8_CHECK Do not check the pattern for UTF-8
validity (only relevant if
PCRE_UTF8 is set)
PCRE must be built with UTF-8 support in order to use PCRE_UTF8 and PCRE_NO_UTF8_CHECK.
The yield of the function is a pointer to a private data structure that contains the compiled pattern, or NULL if an error was detected.
Note that compiling regular expressions with one version of PCRE for use with a different version is not guaranteed to work and may cause
crashes.
There is a complete description of the PCRE native API in the pcreapi page and a description of the POSIX API in the pcreposix page.
