[MPlayer-dev-eng] Pausing command

[jacob]

Please, could any one tell me what does mplayer do in this part of
source code of input/input.c?

 if (strncmp(str, "pausing ", 8) == 0) {
    pausing = 1;
    str = &str[8];
  } else if (strncmp(str, "pausing_keep ", 13) == 0) {
    pausing = 2;
    str = &str[13];
  } else if (strncmp(str, "pausing_toggle ", 15) == 0) {
    pausing = 3;
    str = &str[15];
  }

what differences are there between the different pausings?

Thanks in advance.
