SYNOPSIS
</b><br>
<P>
<b>#include &#60;pcre2.h&#62;</b>
</P>
<P>
<b>int pcre2_set_max_varlookbehind(pcre2_compile_context *<i>ccontext</i>,</b>
<b>  uint32_t <i>value</i>);</b>
</P>

DESCRIPTION
</b><br>
<P>
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>
<P>
There is a complete description of the PCRE2 native API in the
<a href="pcre2api.html"><b>pcre2api</b></a>
page and a description of the POSIX API in the
<a href="pcre2posix.html"><b>pcre2posix</b></a>
page.
