PC Card event codes are event codes that card services sends to the stream interface driver's callback function to indicate that a PC Card event has occurred. Not all event codes are supported on all platforms. The following table shows the defined codes.
| Event code | Description |
|---|---|
| CE_BATTERY_DEAD | Indicates a dead battery on the PC Card. This event is signaled through the BVD1 pin, which can be accessed through the pin replacement register (PRR), also. |
| CE_BATTERY_LOW | Indicates a low battery on the PC Card. This event is signaled through the BVD2 pin, which can be accessed through the PRR, also. |
| CE_CARD_LOCK | Indicates that the hardware card lock is closed. |
| CE_CARD_READY | Indicates that a PC Card has changed from a busy to a ready state. |
| CE_CARD_REMOVAL | Indicates that a PC Card has been removed from the socket. |
| CE_CARD_UNLOCK | Indicates that the hardware card lock is open. |
| CE_PM_SUSPEND | Indicates that the system has just returned from a suspended state and that any CE_CARD_INSERTION and CE_CARD_REMOVAL codes received before the next CE_PM_RESUME code are likely to be invalid. |
| CE_PM_RESUME | Indicates that the system has resumed after being turned off and is now running. |
| CE_EXCLUSIVE_COMPLETE | Indicates that a driver's CardRequestExclusive request has taken place. |
| CE_EXCLUSIVE_REQUEST | Indicates that a driver has called CardRequestExclusive with a request for exclusive access to a PC Card. |
| CE_WRITE_PROTECT | Indicates that a PC Card's write-protect status has changed. |
| CE_CARD_INSERTION | Indicates that a PC Card has been inserted in the socket. Applications registering for insertion events also receive this event for cards that are already in the socket after a suspend event or resume event. |
| CE_REGISTRATION_COMPLETE | Indicates that client registration is complete. |
