Memcpy try catch

WebThe memcpy function copies n bytes from memory area src to memory area dest. This can be unsafe when the size being parsed is not appropriately validated, allowing an attacker to fully control the data and length being passed through. U-Boot contains hundreds of calls to memcpy and libc functions that read from the network such as ntohl and ntohs. WebC++ Try Catch statement is used as a means of exception handling. You may come across some exceptional situations where you may not have control of the values for a variable or such. And this could result in anomalies that C++ cannot execute. In such conditions, C++ throws an exception, and could stop the execution of program.
