records. These files contain structure, the key elements of the structure are given below:
char ut_user[] User login name
char ut_id[] Unique Id to distinguish an entry
char ut_line[] Device name
pid_t ut_pid Process Id
short ut_type Type of Entry
struct ut_exit The exit status of a process

#define BTMPS_FILE "/var/adm/btmps"
Note that and tend to grow without bound, and should be checked regularly. Information that is no longer useful should be removed periodi-
cally to prevent the file from becoming too large. Also note that and are not created by the programs that maintain them. Thus, if these
files are removed, login record-keeping is turned off.
