.TH PCRE2_SET_COMPILE_RECURSION_GUARD 3 "22 October 2014" "PCRE2 10.00"
|

.SH NAME
|
|
PCRE2 - Perl-compatible regular expressions (revised API)
|

.SH SYNOPSIS
|
|
.rs
|

.sp
|
|
.B #include <pcre2.h>

|
.PP
|
|
.nf
|
|
.B int pcre2_set_compile_recursion_guard(pcre2_compile_context *\fIccontext\fP,

.SH DESCRIPTION
|
|
.rs
|
|
.sp
|
|
This function defines, within a compile context, a function that is called
|
|
whenever \fBpcre2_compile()\fP starts to compile a parenthesized part of a
|
|
pattern. The first argument to the function gives the current depth of
|
|
parenthesis nesting, and the second is user data that is supplied when the
|
|
function is set up. The callout function should return zero if all is well, or
|
|
non-zero to force an error. This feature is provided so that applications can
|
|
check the available system stack space, in order to avoid running out. The
|
|
result of \fBpcre2_set_compile_recursion_guard()\fP is always zero.
