I want to find “\r\n\r\n” in a HTTP header.
I know it’s at the end of the packet, so if I reverse search “\r\n\r\n” I’ll get good performance.
Is there a function implement reverse search in C or C++ ?
If so, which one?
Thanks.
Reverse searching for “\r\n\r\n” might give you wrong result. It is not correct logic, because the HTTP body might contain “\r\n\r\n”.
