Re: [Boost-users] regex_search on non-NULL terminated strings.

John,

Thanks very much - this is almost what we want. We did notice that if
there is a null before the end, the search does not stop. Any way to
overcome that? We wouldn't mind doing a strlen(), but that is prone to
failure, so something like strlen_s() or a safe strlen would help. But
strlen_s() is not available in Microsoft MSDN 7.1.

Thanks again,

-venkat

Yes, don't pass a single const char*, but a pair of iterators: a pair of

const char*'s will do just fine if that's the data type you have to hand
- 
the first will point to the start of the string, the second to the point

where you want searching to stop.

HTH, John.
