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.
