PCRE2 - Perl-compatible regular expressions (revised API)

.SH DESCRIPTION
|
||
|
|
.rs
|
||
|
|
.sp
|
||
|
|
This function matches a compiled regular expression that has been successfully
|
||
|
|
processed by the JIT compiler against a given subject string, using a matching
|
||
|
|
algorithm that is similar to Perl's. It is a "fast path" interface to JIT, and
|
||
|
|
it bypasses some of the sanity checks that \fBpcre2_match()\fP applies.
|
||
|
|
Its arguments are exactly the same as for
|
||
|
|
.\" HREF
|
||
|
|
\fBpcre2_match()\fP
|
||
|
|
.\"
|
||
|
|
plus one additional argument that must either point to a JIT stack or be NULL.
|
||
|
|
In the latter case, if a callback function has been set up by
|
||
|
|
\fBpcre2_jit_stack_alloc()\fP, it is called. Otherwise the system stack is
|
||
|
|
used.
|
||
|
|
.P
|
||
|
|
The supported options are PCRE2_NOTBOL, PCRE2_NOTEOL, PCRE2_NOTEMPTY,
|
||
|
|
PCRE2_NOTEMPTY_ATSTART, PCRE2_PARTIAL_HARD, and PCRE2_PARTIAL_SOFT. Unsupported
|
||
|
|
options are ignored. The subject string is not checked for UTF validity.
|
||
|
|
.P
|
||
|
|
The return values are the same as for \fBpcre2_match()\fP plus
|
||
|
|
PCRE2_ERROR_JIT_BADOPTION if a matching mode (partial or complete) is requested
|
||
|
|
that was not compiled. For details of partial matching, see the
|
||
|
|
.\" HREF
