You can use c_str() function of std::string to get the char* out of string. This method basically returns a pointer to c-style string. After this you can use the normal string copying functions such as strcpy or strncpy to copy the value in to test.

You can almost certainly give it a pointer to the std::string's buffer (a char*), safely casted to unsigned char* (though be careful to read what this library function does and ensure it's compatible with the constraints placed upon you by std::string). Have you explored this option?

The c_str variable is used to traverse the character string containing the command line to be parsed. As characters are retrieved from this pointer, they are stored in a variable of type int.For implementations in which the char type is defined to have the same range, representation, and behavior as signed char, this value is sign-extended when assigned to the int variable.
