30 * Known contributors to this file:
39 #include "prototypes.h"
42 * Receive a line of input from the current player.
43 * If the player's aborted flag is set, return -2 without receiving
45 * Else receive one line and store it in CMD[SIZE].
46 * This may block for input, yielding the processor. Flush buffered
47 * output when blocking, to make sure player sees the prompt.
48 * If the player's connection has the I/O error indicator set, or the
49 * line is "aborted", set the player's aborted flag and return -2.
50 * If the player's connection has the EOF indicator set, or the line
51 * is "ctld", return -1.
52 * Else return the length of the line.
53 * Design bug: there is no way to indicate truncation of a long line.
