s32 EXIGetType(s32 chan, u32 dev, u32* type);

Arguments

*`chan`*	EXI channel number.
*`dev`*	EXI device number. (If Slot A or Slot B, specify zero).
*`type`*	Pointer to the EXI device type to retrieve.

The following table shows the relationships between the Revolution extended interface, EXI channel, and device number.

Extended Interface	Channel Number	Device Number
Slot A	0	0
Slot B	1	0
Serial Port 2	2	0

Return Values

Returns 0 if the device ID is still inactive. (In other words, the OS is still checking whether the device is inserted in the slot.) Returns a non-zero if the device type is active. The non-zero return value remains the same until the current device is replaced.

Description

Returns current EXI device type.
