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.
