DEVNAMES-type variables store some information about a device. This information includes the device driver name, the device name, and the names of any output ports it uses. Note that instead of storing strings in the usual way, this structure puts all three strings into extra, where null characters separate them. The offset values specify the location of these strings in extra, measured in bytes from the beginning of the structure. For example, the very first character in extra would have an offset of 8. See the example for the PrintDlg function for a demonstration of using this structure.

wDriverOffset

The offset of the string in extra identifying the name of the device driver filename (without the extension).

wDeviceOffset

The offset of the string in extra identifying the name of the device.

wOutputOffset

The offset of the string in extra identifying the output port(s) which the device uses, separated by commas.

wDefault

If non-zero, the information in the structure identifies the default device of its type. If zero, the information does not necessarily descibe the default device.

extra

Buffer which holds the three strings identified by wDriverOffset, wDeviceOffset, and wOutputOffset.
