NAME
       ustrncat - Concatenates a string to another one, specifying size. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       char *ustrncat(char *dest, const char *src, int n);

DESCRIPTION
       This  function  is  like ustrcat() except that no more than `n' characters from `src' are appended to the end of `dest'. If the terminating
       null character in `src' is reached before `n' characters have been written, the null character is copied, but no other characters are writ-
       ten. If `n' characters are written before a terminating null is encountered, the function appends its own null character to `dest', so that
       `n+1' characters are written. You should try to avoid this function because it is very easy to overflow the destination buffer. Use ustrzn-
       cat instead.

RETURN VALUE
       The return value is the value of `dest'.
