utmpx.h, utmpx - user accounting database definitions
SYNOPSIS
#include <utmpx.h>
DESCRIPTION
The <utmpx.h> header defines the utmpx structure, which includes the following members:
char ut_user[] /* user login name */
char ut_id[] /* unspecified initialization process identifier */
char ut_line[] /* device name */
pid_t ut_pid /* process ID */
short ut_type /* type of entry */
struct timeval ut_tv /* time entry was made */
The pid_t type is defined through typedef as described in <sys/types.h>.
The timeval structure is defined as described in <sys/time.h>.
Inclusion of the <utmpx.h> header can also make visible all symbols from <sys/time.h>.
The following symbolic constants are defined as possible values for the ut_type member of the utmpx structure:
