NAME
PCRE2 - Perl-compatible regular expressions (revised API)
SYNOPSIS
#include <pcre2.h>
int pcre2_set_max_varlookbehind(pcre2_compile_context *ccontext,
uint32_t value);
DESCRIPTION
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.
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.
