Use passwdexpired system call
If you can write a C program, you can call the passwdexpired() system call to get this information. See:

Help -

Here's a code fragment that does the trick. Unfortunately, due to employer restrictions, I can't share the whole code with you. I hacked this out of an existing module, so it is illustrative only.

/* typical includes needed by C programs */
#include <string.h>
#include <ctype.h>
#include <sys/types.h>
#include <time.h>
#include <stdio.h>
#include <errno.h>
#include <stdlib.h>
#include <unistd.h>
#include <time.h>

/* this is the include needed for passwdexpired */
#include <usersec.h>

void main( int argc, char* argv[]) {
char* userid=argv[1];

char p[100] = "";
int rc;

rc = putenv( "LANG=C" ); /* force LANG=C */

/* get password date expiration string */
rc = passwdexpired( userid, &p );
if ( rc == 1 || rc == 2 )
{
printf( "%s\nReset the password \n", p);
exit( 2 );
}

/* some other error */
if ( rc != 0 )
{
if ( errno == ENOENT || errno == ESRCH )
{
fprintf( stderr, "User %s is not defined\n", userid );
}
else
{
fprintf( stderr, "passwdexpired() rc=%d, %s\n", rc, strerror(errno) );
}
exit( 1 );
}

printf( "passwdexpired returned message:\n'%s'\n", p );

}

The binary file must be setuid root, else root must run the program.

pwscore

PWSCORE(1)						      General Commands Manual							PWSCORE(1)

NAME

       pwscore - simple configurable tool for checking quality of a password

SYNOPSIS

       pwscore [user]

DESCRIPTION

       pwscore is a simple tool for checking quality of a password. The password is read from stdin.

       The  tool  uses the libpwquality library to perform configurable checks for minimum length, dictionary checking against cracklib dictionar-
       ies, and other checks.

       It either reports an error if the password fails any of the checks, or it prints out the password quality score as an integer value between
       0 and 100.

       The  password  quality  score is relative to the minlen setting in the configuration file. But in general values below 50 can be treated as
       moderate quality and above it fairly strong quality. Any password that passes the quality checks (especially the mandatory cracklib  check)
       should withstand dictionary attacks and scores above 50 with the default minlen setting even fast brute force attacks.

OPTIONS

       The first and only optional argument is the user name that is used to check the similarity of the password to the username.

FILES

       /etc/security/pwquality.conf - The configuration file for the libpwquality library.

RETURN CODES

       pwscore returns 0 on success, non zero on error.
