Using a String in the Place of a Char *

[PetrolMan]

I'm playing around with a function that requires a char * as input. The function reads some information and dumps it into the char *. I was wondering if there is a way to use a string in the place of a char *. It's not really necessary but I was just kind of curious.

Thanks in advance,

If you've got a string, you can easily turn it into a char* by doing strname.c_str(). Is that what you're looking for?

Unfortunately, no, std::string::c_str() returns a const char*, and the function in question modifies the C-style string. Furthermore, at the moment the characters stored in std::string are not required to be contiguous (unlike the elements of std::vector), so you cannot safely just pass &str[0] to the function, where str is the name of your std::string.
