Sleep Queue Record

The SleepQInstall and SleepQRemove procedures take as a parameter the address of a sleep queue record, which is defined by the SleepQRec data type.

TYPE SleepQRec = 
   RECORD
      sleepQLink:    SleepQRecPtr;  {next queue element}
      sleepQType:    Integer;       {queue type = 16}
      sleepQProc:    ProcPtr;       {pointer to sleep procedure}
      sleepQFlags:   Integer;       {reserved}
   END;
   SleepQRecPtr = ^SleepQRec;
