KD is the IOS module responsible for implementing WiiConnect24 functionality. It can perform HTTP(S) downloads, send and receive mail via SMTP, and execute a JavaScript-like language while the Wii is in standby mode.
Ioctl listing
Inbuf addr & 3 is written to outbuf for most or all ioctls.
| Request number | Name | Input | Output | Notes |
|---|---|---|---|---|
| 1 | ExecSuspendScheduler | none | 4 bytes | |
| 2 | ExecTrySuspendScheduler | 32 bytes | 32 bytes | |
| 3 | ExecResumeScheduler | none | 4+ bytes | |
| 4 | KD_GetTimeTriggers | ? | 12 bytes | Writes the time triggers for the minutes of the hour for when KD_Download and KD_CheckMail are triggered to outbuf + 4. |
| 5 | ? | ? | 4+ bytes | |
| 6 | NWC24iStartupSocket | none | 32 bytes | |
| 7 | NWC24iCleanupSocket | none | 32 bytes | |
| 8 | NWC24iLockSocket | none | 32 bytes | |
| 9 | NWC24iUnlockSocket | none | 32 bytes | |
| 0xa | NWC24iCheckMailNow | none | 32 bytes | |
| 0xb | NWC24iSendMailNow | none | 8+ bytes | Connect and send mail? |
| 0xc | NWC24iReceiveMailNow | ? | 8+ bytes | |
| 0xd | NWC24iSaveMailNow | none | 32 bytes | |
| 0xe | NWC24iDownloadNowEx | 32 bytes | 32 bytes | inbuf + 0 u32 is flags, inbuf + 6 u16 is nwc24dl.bin entry index, inbuf + 8 u32 is subTask bitmask. Starting at outbuf + 8 is a buffer of unknown size. Flags bit 1 must be set to manually specify a task/entry. When clear, a task is chosen automatically with the same mechanism used for choosing a task in the background.(When bit 1 is clear with this ioctl from Broadway, nothing will be downloaded since no entries will be ready for download due to dl frequencies fields.) subTask bitmap is a bitmap of subTasks to download, so setting bit 0 will download subTask zero, and so on. |
