Added new feature (proc_args) to get command line arguments:

typedef struct _glibtop_proc_args	glibtop_proc_args;

struct _glibtop_proc_args
{
	u_int64_t	flags,
		size;			/* GLIBTOP_PROC_ARGS_SIZE	*/
};

Returns a string containing all command line arguments of the process,
the `unsigned' parameter is the maximum length of this string; if it
is zero then no limit will be set.

extern const char  *glibtop_get_proc_args_l __P((glibtop *, glibtop_proc_args *, pid_t, unsigned));
