.TH PCRE2_SET_MAX_PATTERN_LENGTH 3 "05 October 2016" "PCRE2 10.23"
.SH NAME
PCRE2 - Perl-compatible regular expressions (revised API)
.SH SYNOPSIS
.rs
.sp
.B #include <pcre2.h>
.PP
.nf
.B int pcre2_set_max_pattern_length(pcre2_compile_context *\fIccontext\fP,
.B "  PCRE2_SIZE \fIvalue\fP);"
.fi
.
.SH DESCRIPTION
.rs
.sp
This function sets, in a compile context, the maximum text length (in code
units) of the pattern that can be compiled. The result is always zero. If a
longer pattern is passed to \fBpcre2_compile()\fP there is an immediate error
return. The default is effectively unlimited, being the largest value a
PCRE2_SIZE variable can hold.
.P
There is a complete description of the PCRE2 native API in the
