UTEMPTER(3) BSD Library Functions Manual UTEMPTER(3) NAME
utempter_add_record, utempter_remove_added_record, utempter_remove_record, utempter_set_helper -- utempter interface SYNOPSIS
#include <utempter.h> int utempter_add_record(int fd, const char *host); int utempter_remove_added_record(void); int utempter_remove_record(int fd); void utempter_set_helper(const char *pathname); DESCRIPTION
utempter_add_record() function adds a login record to the database for the TTY belonging to the pseudo-terminal master file descriptor fd, using the username corresponding with the real user ID of the calling process and the optional hostname host. This function spawns a privi- leged process to perform the actual logging. utempter_remove_record() function marks the login session as being closed for the TTY belonging to the pseudo-terminal master file descriptor fd. This function spawns a privileged process to perform the actual logging. utempter_remove_added_record() function has the same properties as the previously mentioned function, except that it uses an internally cached value of the file descriptor passed to the login functions. utempter_set_helper() function changes default helper path to the specified value. The pointer passed to this function must remain valid all the time while utempter interface is in use. RETURN VALUES
On error, zero is returned. On success, a non-zero value is returned. NOTES
During execution of the privileged process spawned by these functions, SIGCHLD signal handler will be temporarily set to the default action. SEE ALSO

UTEMPTER_ADD_RECORD(3) BSD Library Functions Manual UTEMPTER_ADD_RECORD(3) NAME
utempter_add_record, utempter_remove_added_record, utempter_remove_record, addToUtmp, removeFromUtmp, removeLineFromUtmp -- utempter compati- bility interface LIBRARY
User Login Record Library (libulog, -lulog) SYNOPSIS
#include <utempter.h> int utempter_add_record(int fd, const char *host); int utempter_remove_added_record(void); int utempter_remove_record(int fd); void addToUtmp(const char *pty, const char *host, int fd); void removeFromUtmp(void); void removeLineFromUtmp(const char *pty, int fd); DESCRIPTION
The utempter_add_record() and addToUtmp() functions add a login record to the database for the TTY belonging to the pseudo-terminal master file descriptor fd, using the username corresponding with the real user ID of the calling process and the optional hostname host. These functions are equivalent to ulog_login_pseudo(3). The utempter_remove_record() and removeLineFromUtmp() functions mark the login session as being closed for the TTY belonging to the pseudo- terminal master file descriptor fd. These functions are equivalent to ulog_logout_pseudo(3). The utempter_remove_added_record() and removeFromUtmp() functions have the same properties as the previously mentioned functions, except that they use an internally cached value of the file descriptor passed to the login functions. The pty arguments of addToUtmp() and removeLineFromUtmp() are unused. RETURN VALUES
In this implementation, the utempter_add_record(), utempter_remove_added_record() and utempter_remove_record() always return a value of 0. SEE ALSO
