Regular Expressions

Note

These functions are deprecated and will be removed in a future release. If you have concerns, open a ticket and provide feedback at https://supporttickets.intel.com/.

This section describes the Intel IPP functions that perform matching operations with the Perl-compatible regular expression patterns. See http://search.cpan.org/dist/perl/pod/perlre.pod for more details about Perl-compatible regular expressions.

The current version of the Intel IPP functions for regular expressions have some limitations, specifically they do not support literal (metacharacters \l, \L, \u, \U, \N{name}), embedded Perl code (?{code}), extended regular expression ( ??{code}).
