Hi Greg,
here is a patch for inserting the callout output into NAME=.
ID= supports the usual wildcard to compare with the output.

I've moved all wildcard matching to a function cause this was the third occurrence.
Also attached is the last whitespace cleanup and debug text corrections.
The callout patch depends on the whitespace patch.


CALLOUT, BUS="usb", PROGRAM="/bin/echo -n return", ID="ret*", NAME="webcam-%c-"

results in:

Nov 21 17:33:51 pim udev[20399]: get_major_minor: found major = 81, minor = 0
Nov 21 17:33:51 pim udev[20399]: exec_callout: callout to '/bin/echo -n return'
Nov 21 17:33:51 pim udev[20399]: exec_callout: callout returned 'return'
Nov 21 17:33:51 pim udev[20399]: get_attr: substitute callout output 'return'
Nov 21 17:33:51 pim udev[20399]: udev_add_device: name = webcam-return-
Nov 21 17:33:51 pim udev[20399]: create_node: mknod(/udev/webcam-return-, 020660, 81, 0)


thanks,
Kay
