The manpages are out of date -- see Ulrich Drepper's post:

Called from C++, you have to do the following:
- include <cstring> rather than <string.h>
- if you pass in a const char *, the output should be stored in a
const char * variable
- otherwise, the output should be assigned to a char * variable
