: text name associated with the /proc entry
dgrp_proc_entry: structure for dgrp proc dirs : ID number associated with this particular entry. Should be unique across all of DGRP. : file access permisssions for the /proc entry : pointer to table describing a subdirectory for this entry : pointer to directory entry for this object once registered. Used to grab the handle of the object for unregistration : semaphore to provide exclusive to struct : counter of current accesses Each entry in a DGRP proc directory is described with a dgrp_proc_entry structure. A collection of these entries (in an array) represents the members associated with a particular /proc directory, and is referred to as a table. All tables are terminated by an entry with zeros for every member.

void dgrp_carrier ( struct ch_struct * ch )

dgrp_carrier – check for carrier change state and act : struct ch_struct *

Definition at line 47 of file dgrp_common.c.

int dgrp_chk_perm	(	int	mode,
		int	op
	)

dgrp_chk_perm() – check permissions for net device : pointer to inode structure for the net communication device : operation to be tested

The file permissions and ownerships are tested to determine whether the operation "op" is permitted on the file pointed to by the inode. Returns 0 if the operation is permitted, -EACCESS otherwise

void dgrp_poll_handler ( unsigned long arg )

dgrp_poll_handler() – handler for poll timer

As each timer expires, it determines (a) whether the "transmit" waiter needs to be woken up, and (b) whether the poller needs to be rescheduled.
