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.

Actually, login does a LIOCTTYI ioctl (on the LAT tty fd) and stores the resultant information in the wtmp/utmp files from which w and last display the server name. lcp(8) -p uses LIOCGSRVPRT ioctl on (AF_LAT, SOCK_DGRAM, LATPROTO_CTL) socket with lsp_dev set to the LAT tty to be queried. -- Matt Thomas Internet: thomas@wrl.dec.com DECnet-ULTRIX Development UUCP: ...!decwrl!thomas Digital Equipment Corporation Disclaimer: This message reflects my own Littleton, MA warped views, etc.
