In this case you have a problem.
c_str() gives a const char*
but your Load function wants an unsigned char* (which is not const).

You now have 4 options:
* create a copy of the string in dynamic memory and pass a pointer
  to that to the Load function
* if you are 100% sure that the function will not alter the passed characters
  you can cast away the const (by using a const_cast)
* use a different library
* contact the author of the library and ask him to change the argument list.
