GETPASS(3C) (C Programming Language Utilities) GETPASS(3C)
NAME
getpass - read a password
SYNOPSIS
char *getpass (prompt)
char *prompt;
DESCRIPTION
getpass reads up to a newline or EOF from the file /dev/tty,
after prompting on the standard error output with the null-
terminated string prompt and disabling echoing. 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.
