PCRE2_GET_STARTCHAR(3) FreeBSD Library Functions Manual
NAME
PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
#include <pcre2.h>
PCRE2_SIZE pcre2_get_startchar(pcre2_match_data *match_data);
DESCRIPTION
After a successful call of pcre2_match() that was passed the match
block that is this function's argument, this function returns the code
unit offset of the character at which the successful match started. For
a non-partial match, this can be different to the value of ovector[0]
if the pattern contains the \K escape sequence. After a partial match,
however, this value is always the same as ovector[0] because \K does
not affect the result of a partial match.
There is a complete description of the PCRE2 native API in the pcre2api
page and a description of the POSIX API in the pcre2posix page.
