Allow watch(8) to use more than 10 snp* devices. This limitation was purely due to the way watch(8) looks for available snoop devices. PR: bin/118286 Submitted by: Mykola Zubach Reviewed by: rwatson, csjp, imp (all a long time ago) Approved by: imp (mentor) (long time ago)

By default, the watch utility will attempt to open /dev/snp0, if

2004-08-10T01:49:46Z

another process already has /dev/snp0 open, the snp(4) will return EBUSY, in which case watch will try to open /dev/snp1..9. Currently watch does not check errno to see if the failure was a result of EBUSY. This results in watch making futile attempts to open snp0..snp9 even though devices may not exist or the caller does not have permissions to access the device. In addition to this, it attempts to setup the screen for snooping even though it may not ever get an snp device. So this patch does two things 1) Checks errno for EBUSY, if open(2) fails for another reason print that reason and exit. 2) setup the terminal for snooping after the snp descriptor has been obtained.
