NAME

       updwtmp, logwtmp - append an entry to the wtmp file

SYNOPSIS

       #include <utmp.h>

       void updwtmp(const char *wtmp_file, const struct utmp *ut);
       void logwtmp(const char *line, const char *name, const char *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.  However, logwtmp occurs in the old
       libbsd.
