.TH PCRE 3
.SH NAME
PCRE - Perl-compatible regular expressions
.SH SYNOPSIS
.rs
.sp
.B #include <pcre.h>
.PP
.SM
.br
.B int pcre_exec(const pcre *\fIcode\fR, "const pcre_extra *\fIextra\fR,"
.ti +5n
.B "const char *\fIsubject\fR," int \fIlength\fR, int \fIstartoffset\fR,
.ti +5n
.B int \fIoptions\fR, int *\fIovector\fR, int \fIovecsize\fR);
.SH DESCRIPTION
.rs
.sp
This function matches a compiled regular expression against a given subject
string, and returns offsets to capturing subexpressions. Its arguments are:
\fIcode\fR Points to the compiled pattern
\fIextra\fR Points to an associated \fBpcre_extra\fR structure,
or is NULL
\fIsubject\fR Points to the subject string
\fIlength\fR Length of the subject string, in bytes
\fIstartoffset\fR Offset in bytes in the subject at which to
start matching
\fIoptions\fR Option bits
\fIovector\fR Points to a vector of ints for result offsets
\fIovecsize\fR Size of the vector (a multiple of 3)
The options are:
PCRE_ANCHORED Match only at the first position
PCRE_NOTBOL Subject is not the beginning of a line
PCRE_NOTEOL Subject is not the end of a line
PCRE_NOTEMPTY An empty string is not a valid match
PCRE_NO_UTF8_CHECK Do not check the subject for UTF-8
validity (only relevant if PCRE_UTF8
was set at compile time)
There is a complete description of the PCRE API in the
.\" HREF
