ustrzncpy
Copies a string into another one, specifying size.
Description
char *ustrzncpy(char *dest,
int size,
const char *src,
int n
);
This function is like ustrzcpy() except that no more than `n' characters
from `src' are copied into `dest'. If `src' is shorter than `n' characters,
null characters are appended to `dest' as padding until `n' characters have
been written. In any case, `dest' is guaranteed to be null-terminated.
Note that, even for empty strings, your destination string must have at
least enough bytes to store the terminating null character of the string,
and your parameter `size' must reflect this. Otherwise, the debug version
of Allegro will abort at an assertion, and the release version of Allegro
will overrun the destination buffer.
The return value is the value of `dest'.
