NetBSD 6.1.5 - man page for updwtmpx (netbsd section 3)

GETLASTLOGX(3)			   BSD Library Functions Manual 		   GETLASTLOGX(3)

     getlastlogx, getutmp, getutmpx, updlastlogx, updwtmpx, utmpxname -- user accounting database

     Standard C Library (libc, -lc)

     #include <utmpx.h>

     struct lastlogx *
     getlastlogx(const char *fname, uid_t uid, struct lastlogx *ll);

     getutmp(const struct utmpx *ux, struct utmp *u);

     getutmpx(const struct utmp *u, struct utmpx *ux);

     updlastlogx(const char *fname, uid_t uid, struct lastlogx *ll);

     updwtmpx(const char *file, const struct utmpx *utx);

     utmpxname(const char *fname);

     The getlastlogx() function looks up the entry for the user with user id uid in the
     lastlogx(5) file given by fname and returns it in ll.  If the provided ll is NULL, the nec-
     essary space will be allocated by getlastlogx() and should be free()d by the caller.

     The getutmp() function fills out the entries in the struct utmp u with the data provided in
     the struct utmpx ux.  getutmpx() does the opposite, filling out the entries in the struct
     utmpx ux with the data provided in the struct utmp u, and initializing all the unknown
     fields to 0.  The sole exception is the ut_type field, which will be initialized to

     The updlastlogx() function tries to update the information for the user with the user id uid
     in the lastlogx(5) file given by fname with the data supplied in ll.  A struct lastlogx is
     defined like this:

     struct lastlogx {
	     struct timeval ll_tv;	     /* time entry was created */
	     char ll_line[_UTX_LINESIZE];    /* tty name */
	     char ll_host[_UTX_HOSTSIZE];    /* host name */
	     struct sockaddr_storage ll_ss;  /* address where entry was made from */
     All the fields should be filled out by the caller.

     The updwtmpx() function updates the wtmpx(5) file file with the utmpx(5) entry utx.

     The utmpxname() function sets the default utmpx(5) database file name to fname.

     getlastlogx() returns the found entry on success, or NULL if it could not open the database,
     could not find an entry matching uid in there, or could not allocate the necessary space (in
     case ll was NULL).

     utmpxname() returns 1 on success, or 0 if the supplied file name was too long or did not end
     with 'x'.

     updlastlogx() and updwtmpx() return 0 on success, or -1 in case the database or file respec-
     tively could not be opened or the data not written into it.

     endutxent(3), loginx(3), utmpx(5)

     The functions getutmp(), getutmpx(), updwtmpx(), and utmpxname() first appeared in Solaris.
     getlastlogx and updlastlogx first appeared in NetBSD 2.0.
