UPDWTMP(3) Linux Programmer's Manual UPDWTMP(3)
NAME
updwtmp, logwtmp - append an entry to the wtmp file
SYNOPSIS
#include<utmp.h>
voidupdwtmp(constchar*wtmp_file,conststructutmp*ut);
voidlogwtmp(constchar*line,constchar*name,constchar*host);
DESCRIPTION
updwtmp() appends the utmp structure ut to the wtmp file.
logwtmp() constructs an utmp structure using line, name, host, current
time and current process id. Then it calls updwtmp() to append the
structure to the utmp file.
AVAILABILITY
Both functions are available under glibc2, but not under libc5. How-
ever, logwtmp occurs in the old libbsd.
