.SH SYNOPSIS

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

|
|

.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.
