.SH SYNOPSIS
.rs
.sp
.B #include <pcre.h>
.PP
.SM
.br
.B pcre *pcre_compile(const char *\fIpattern\fR, int \fIoptions\fR,
.ti +5n
.B const char **\fIerrptr\fR, int *\fIerroffset\fR,
.ti +5n
.B const unsigned char *\fItableptr\fR);
.SH DESCRIPTION
.rs
.sp
This function compiles a regular expression into an internal form. Its
arguments are:
\fIpattern\fR A zero-terminated string containing the
regular expression to be compiled
\fIoptions\fR Zero or more option bits
\fIerrptr\fR Where to put an error message
\fIerroffset\fR Offset in pattern where error was found
\fItableptr\fR Pointer to character tables, or NULL to
use the built-in default
The option bits are:
PCRE_ANCHORED Force pattern anchoring
PCRE_CASELESS Do caseless matching
PCRE_DOLLAR_ENDONLY $ not to match newline at end
PCRE_DOTALL . matches anything including NL
PCRE_EXTENDED Ignore whitespace and # comments
PCRE_EXTRA PCRE extra features
(not much use currently)
PCRE_MULTILINE ^ and $ match newlines within data
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 must have been compiled with UTF-8 support when PCRE_UTF8 is used.
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.
There is a complete description of the PCRE API in the
.\" HREF
