IEEE80211_DDB(9)					   BSD Kernel Developer's Manual					  IEEE80211_DDB(9)

NAME

     ieee80211_ddb -- 802.11 ddb support

SYNOPSIS

     options DDB

     show vap [addr]
     show all vaps
     show com [addr]
     show sta [addr]
     show statab [addr]
     show mesh [addr]

DESCRIPTION

     The net80211 layer includes ddb(4) support for displaying important data structures.  This is especially important because wireless applica-
     tions are often built for embedded environments where cross-machine or post-mortem debugging facilities like kgdb(1) are infeasible.

     The most commonly used command is

	   show all vaps/a

     which dumps the contents of all ieee80211vap, ieee80211com, and ieee80211_node data structures in the system.

DB_COMMAND(9)						   BSD Kernel Developer's Manual					     DB_COMMAND(9)

NAME

     DB_COMMAND, DB_SHOW_COMMAND, DB_SHOW_ALL_COMMAND -- Extends the ddb command set

SYNOPSIS

     #include <ddb/ddb.h>

     DB_COMMAND(command_name, command_function);

     DB_SHOW_COMMAND(command_name, command_function);

     DB_SHOW_ALL_COMMAND(command_name, command_function);

DESCRIPTION

     The DB_COMMAND() macro adds command_name to the list of top-level commands.  Invoking command_name from ddb will call command_function.

     The DB_SHOW_COMMAND() and DB_SHOW_ALL_COMMAND() are roughly equivalent to DB_COMMAND() but in these cases, command_name is a sub-command of
     the ddb show command and show all command, respectively.

     The general command syntax: command[/modifier] address[,count], translates into the following parameters for command_function:

	   addr 	 The address passed to the command as an argument.

	   have_addr	 A boolean value that is true if the addr field is valid.

	   count	 The number of quad words starting at offset addr that the command must process.

	   modif	 A pointer to the string of modifiers. That is, a series of symbols used to pass some options to the command. For example,
			 the examine command will display words in decimal form if it is passed the modifier "d".

EXAMPLE

     In your module, the command is declared as:

     DB_COMMAND(mycmd, my_cmd_func)
     {
	     if (have_addr)
		     db_printf("Calling my command with address %p
", addr);
     }

     Then, when in ddb:

     db> mycmd 0x1000
     Calling my command with address 0x1000
     db>
