Buffer size: N*sizeof(type) or sizeof(var)? C++
- by flyout
I am just starting with cpp and I've been following different examples to learn from them, and I see that buffer size is set in different ways, for example:
char buffer[255];
StringCchPrintf(buffer, sizeof(buffer), TEXT("%s"), X);
VS
char buffer[255];
StringCchPrintf(buffer, 255*sizeof(char), TEXT("%s"), X);
Which one is the correct way to use it?
I've seen this in other functions like InternetReadFile, ZeroMemory and MultiByteToWideChar.
