replacement pattern in ippsRegExpReplaceInit

Hi,

I'm curious what kinds of replacement patterns IPP supports in ippsRegExpReplaceInit.

The only supported case I found besides raw string is as follows.

regex: ([AB])([CD])
src string: AC
replacement: $2$1
dist string: CA

Is there any other kinds of supported patterns? / What are the exact usages of replacement pattern?

Thanks,
-Evan

Hi,

IPP function perform matching and replacement operations with the Perl-compatible regular expression patterns. For the replacementit is:1. Simple text replacemet and2. Using of n-th matched subpattern ($1, 2,...) in any combination.
