.TH PCRE2_SET_NEWLINE 3 "11 August 2023" "PCRE2 10.45"
.SH NAME
PCRE2 - Perl-compatible regular expressions (revised API)
.SH SYNOPSIS
.rs
.sp
.B #include <pcre2.h>
.PP
.nf
.B int pcre2_set_max_varlookbehind(pcre2_compile_context *\fIccontext\fP,
.B " uint32_t \fIvalue\fP);"
.fi
.
.SH DESCRIPTION
.rs
.sp
This sets a maximum length for the number of characters matched by a
variable-length lookbehind assertion. The default is set when PCRE2 is built,
with the ultimate default being 255, the same as Perl. Lookbehind assertions
without a bounding length are not supported. The result is always zero.
.P
There is a complete description of the PCRE2 native API in the
.\" HREF
\fBpcre2api\fP
.\"
page and a description of the POSIX API in the
.\" HREF
\fBpcre2posix\fP
.\"
page.
