Hi all,
Special thanks to Casper for his guidance.OK, then we just modify the
getresponse () function as below:
********************************************************************************************
char *getresponse(char *oldval)
{
char resp[MAX_INPUT_LEN];
char *retval = NULL;
int resplen;
int c;
c=getchar();
if(c==EOF) {
fprintf(stderr,MSG_CTRL);
passwd_exit(CTRLD);
} else {
(void) fgets(resp, sizeof (resp) - 1, stdin);
resplen = strlen(resp) - 1;
if (resp[resplen] == '\n')
resp[resplen] = '\0';
if (*resp != '\0' && strcmp(resp, oldval) != 0)
retval = strdup(resp);
return (retval);
}
}
************************************************************************************************
And now, we just change the macro MSG_CTRL to
#define MSG_CTRL "\nYou have typed Ctrl-D which is unacceptable\n"
************************************************************************************************
The other macro CTRLD remains the same.
#define CTRLD 11 /*Exit value for typing Ctrl-D*/
*************************************************************************************************
Now when we type 'passwd -e' in the shell and when prompted for a new
shell, we type Ctrl-D, the output is
You have pressed or Ctrl-D which is unacceptable.
Login shell unchanged.
*************************************************************************************************
Hope this solves the bug.
