[Boost-users] cancel a pending cregex_iterator matching

Hello, I am using the following pesudo code to do a regex match on big
buffer (25K of text), sometimes it takes a little longer to come back
with a result. I know this partly because the way my regular
expression pattern is structured, but I am just wondering whether
boost::regex has a mechanism to cancel the pending matching like this
one.

regex expr(const char* key, regex_constants::perl | regex_constants::icase);
cregex_iterator m1(pBuf, pBuf + scope, expr), m2;

if (m1 != m2) {
// A match found
}
else {
// No match found
}
