c++ - How to get the number of bytes occupied by a specific string in the program?

Question

Im using BSPlib and I want to use the bsp_put which requires me to set the size of the string I'm sending. Even if you aren't familiar with BSP, this is not closely related. thanks.

Answer 1

Multiply the number of characters (given by size(), or capacity() if you want to know the total amount allocated rather than the amount in use) by the size of the character type.

If it's std::string itself, an alias for std::basic_string<char>, then the character size is one byte, so size() (or capacity()) alone will do.
