getpass and /dev/tty

getpass and /dev/tty

[Denis Excoffier]

Hello!

Would it be possible that getpass() first reads on /dev/tty before
defaulting to stdin?

% uname -a
CYGWIN_NT-5.1 edited 1.7.12(0.260/5/3) 2012-04-03 10:24 i686 Cygwin
% ls /dev/tt*
/dev/tty  /dev/ttyS0  /dev/ttyS2  /dev/ttyS3
% cat foo.c
#include <stdio.h>
#include <unistd.h>

int main () {
  fprintf (stderr, "Press <Return> to continue . . .\n");
  getpass ("");
  return 0;
};
% gcc -O -o ./foo foo.c
% ./foo
Press <Return> to continue . . .
[here you press Return]

% ./foo < /dev/null
Press <Return> to continue . . .

%

[for the second run of ./foo, you cannot press Return]



Regards,

Denis Excoffier.

Yeah, that makes sense.  I'll rework the function to behave more like
glibc's version of getpass.

would you mind to check the latest snapshot ASAP, if the getpass
function now works as expected for you, not only your testcase, but
also your real-life problem?


Thanks,
Corinna

My real-life problem is not so far than the test case, in particular
i don't use the characters typed in. In any case, both work for me.
Thank you.
