          GETPASS(3C)          INTERACTIVE UNIX System          GETPASS(3C)



          NAME
               getpass - read a password

          SYNOPSIS
               char *getpass (prompt)
               char *prompt;

          DESCRIPTION
               The getpass function reads up to a new-line or EOF from the
               file /dev/tty after prompting on the standard error output
               with the null-terminated string prompt and disabling echo-
               ing.  A pointer is returned to a null-terminated string of
               at most 8 characters.  If /dev/tty cannot be opened, a NULL
               pointer is returned.  An interrupt will terminate input and
               send an interrupt signal to the calling program before
               returning.

          FILES
               /dev/tty

          WARNING
               The above routine uses <stdio.h>, which causes it to
               increase the size of programs not otherwise using standard
               I/O more than might be expected.

          CAVEAT
               The return value points to static data whose content is
               overwritten by each call.
