21 /* TODO:
22 * - implement WINMM (32bit) multitasking and use it in all MCI drivers
23 * instead of the home grown one
24 * - 16bit mmTaskXXX functions are currently broken because the 16
25 * loader does not support binary command lines => provide Wine's
26 * own mmtask.tsk not using binary command line.
27 * - correctly handle the MCI_ALL_DEVICE_ID in functions.
28 * - finish mapping 16 <=> 32 of MCI structures and commands
29 * - implement auto-open feature (ie, when a string command is issued
30 * for a not yet opened device, MCI automatically opens it)
31 * - use a default registry setting to replace the [mci] section in
32 * configuration file (layout of info in registry should be compatible
33 * with all Windows' version - which use different layouts of course)
34 * - implement automatic open
35 * + only works on string interface, on regular devices (don't work on all
36 * nor custom devices)
37 * - command table handling isn't thread safe
