struct lastlogx *
getlastlogx(const char *fname, uid_t uid, struct lastlogx *ll);
void
getutmp(const struct utmpx *ux, struct utmp *u);
void
getutmpx(const struct utmp *u, struct utmpx *ux);
int
updlastlogx(const char *fname, uid_t uid, struct lastlogx *ll);
int
updwtmpx(const char *file, const struct utmpx *utx);
int
utmpxname(const char *fname);
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 USER_PROCESS.
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.
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 respectively could not be opened or the data not written into it.
