将字符串转换为字节数组混淆

Question

How would I properly convert string into byte array? Let's say my buffer holds: \x1c\x1a\x00\ as a string:

std::string newbuffer = buffer; // \x1c\x1a\x00
char test[newbuffer.size()] = newbuffer;

I get 'initializing': cannot convert from 'std::string' to 'char . I tried to follow this here, but I get the same error: https://stackoverflow.com/a/505141/8965047

Answer 1

std::string newbuffer = buffer; // \x1c\x1a\x00
char* test = new char(newbuffer.size()+1);
memcpy(test, newbuffer.c_str(), newbuffer.size());

remember delete char*
