[lvm-devel] LVM2 daemons/clvmd/lvm-functions.c lib/command ...



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	wysochanski sourceware org	2008-12-17 16:46:45

Modified files:
	daemons/clvmd  : lvm-functions.c 
	lib/commands   : toolcontext.c toolcontext.h 
	lib            : lvm2.h 
	tools          : lvmcmdline.c 

Log message:
	Remove struct arg * from struct cmd_context and create_toolcontext().
	
	This allows us to remove one argument from create_toolcontext() and
	moves it closer to a generic library init function.
	
	In the arg_*() functions, we just use _the_args() directly.
	For now we leave the first parameter to these
	arg_*() functions (struct cmd_context *) because
	of the number of files involved in removing the
	parameter.
