+PCRE2 - Perl-compatible regular expressions (revised API)
+.SH SYNOPSIS
+.rs

+.B #include <pcre2.h>
+.PP
+.nf
+.B pcre2_code *pcre2_compile(PCRE2_SPTR \fIpattern\fP, PCRE2_SIZE \fIlength\fP,

+.SH DESCRIPTION
+.rs
+.sp
+This function compiles a regular expression pattern into an internal form. Its
+arguments are:
+.sp
+ \fIpattern\fP A string containing expression to be compiled
+ \fIlength\fP The length of the string or PCRE2_ZERO_TERMINATED
+ \fIoptions\fP Option bits
+ \fIerrorcode\fP Where to put an error code
+ \fIerroffset\fP Where to put an error offset
+ \fIccontext\fP Pointer to a compile context or NULL
+.sp
+The length of the pattern and any error offset that is returned are in code
+units, not characters. A compile context is needed only if you want to provide
+custom memory allocation functions, or to provide an external function for
+system stack size checking, or to change one or more of these parameters:
+.sp
+ What \eR matches (Unicode newlines, or CR, LF, CRLF only);
+ PCRE2's character tables;
+ The newline character sequence;
+ The compile time nested parentheses limit;
+ The maximum pattern length (in code units) that is allowed.
+ The additional options bits (see pcre2_set_compile_extra_options())
+.sp
+The option bits are:
+.sp
+ PCRE2_ANCHORED Force pattern anchoring
+ PCRE2_ALLOW_EMPTY_CLASS Allow empty classes
+ PCRE2_ALT_BSUX Alternative handling of \eu, \eU, and \ex
+ PCRE2_ALT_CIRCUMFLEX Alternative handling of ^ in multiline mode
+ PCRE2_ALT_VERBNAMES Process backslashes in verb names
+ PCRE2_AUTO_CALLOUT Compile automatic callouts
+ PCRE2_CASELESS Do caseless matching
+ PCRE2_DOLLAR_ENDONLY $ not to match newline at end
+ PCRE2_DOTALL . matches anything including NL
+ PCRE2_DUPNAMES Allow duplicate names for subpatterns
+ PCRE2_ENDANCHORED Pattern can match only at end of subject
+ PCRE2_EXTENDED Ignore white space and # comments
+ PCRE2_FIRSTLINE Force matching to be before newline
+ PCRE2_LITERAL Pattern characters are all literal
+ PCRE2_MATCH_UNSET_BACKREF Match unset backreferences
+ PCRE2_MULTILINE ^ and $ match newlines within data
+ PCRE2_NEVER_BACKSLASH_C Lock out the use of \eC in patterns
+ PCRE2_NEVER_UCP Lock out PCRE2_UCP, e.g. via (*UCP)
+ PCRE2_NEVER_UTF Lock out PCRE2_UTF, e.g. via (*UTF)
+ PCRE2_NO_AUTO_CAPTURE Disable numbered capturing paren-
+ theses (named ones available)
+ PCRE2_NO_AUTO_POSSESS Disable auto-possessification
+ PCRE2_NO_DOTSTAR_ANCHOR Disable automatic anchoring for .*
+ PCRE2_NO_START_OPTIMIZE Disable match-time start optimizations
+ PCRE2_NO_UTF_CHECK Do not check the pattern for UTF validity
+ (only relevant if PCRE2_UTF is set)
+ PCRE2_UCP Use Unicode properties for \ed, \ew, etc.
+ PCRE2_UNGREEDY Invert greediness of quantifiers
+ PCRE2_USE_OFFSET_LIMIT Enable offset limit for unanchored matching
+ PCRE2_UTF Treat pattern and subjects as UTF strings
+.sp
+PCRE2 must be built with Unicode support (the default) in order to use
+PCRE2_UTF, PCRE2_UCP and related options.
+.P
+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.
+.P

+each option, in the

+page, and a description of the POSIX API in the
