How do I get lat info from C?

[John Cothran]

   The lat.h include file has several structures defined with lots of goodies.
In particular:

/*
 * LAT parameters data structure for LAT_SERVPORT.
 */
struct lat_servport {
    u_char lsp_name[17];		/* LAT server name */
    u_char lsp_port[17];		/* LAT server port name */
    u_char lsp_serv[17];		/* LAT destination */
    u_char lsp_flags;			/* LAT flags */
#define LSP_DEFAULT_SERVICE	1	/* serve the default service */
#define LSP_HIC			2	/* terminal is for HIC */
#define LSP_APPL_SERVICE	3	/* terminal is for appl service */
    dev_t lsp_dev;			/* LAT tty number */
};

My question is what functions can I call to get this info?  I want to write a
program that will list all users and the server/port they are coming in on.
I assume it can be done since "w" now shows the server name.

   Thanks in advance.  John.
