CHECK_EXPIRE(3) BSD Programmer's Manual CHECK_EXPIRE(3)
check_expire - check for password expiration
#include <stdio.h> #include <util.h> int login_check_expire(FILE *back, struct passwd *pwd, char *class, int lastchance);
The login_check_expire() function is called by a BSD authentication login script to check whether the user's password entry, as described by pwd, has expired. If a class is specified, it is used instead of the class specified in the user's password database entry. If the lastchance argument is non-zero, the user's password has expired, and it has not been expired longer than "password-dead" seconds (see login.conf(5)), the user will be able to log in one last time to change the password.
The login_check_expire() function returns 0 if the user's password has not expired, and 1 if it has expired or if an error occurred. Status and error messages are passed back to the login script caller via the back channel, back.
