 If \fIdst\fR is not a null pointer, the pointer object pointed to by \fIsrc\fR
 is assigned either a null pointer (if conversion stopped due to reaching a
 terminating null character) or the address just past the last character
 converted (if any).  If conversion stopped due to reaching a terminating null
 character, and if \fIdst\fR is not a null pointer, the resulting state
