NAME
|
|
getpass - read a password
|
|
SYNTAX
|
|
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
|
|
SEE ALSO
|
|
crypt(3C).
|
|
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.
|
|
BUGS
|
|
The return value points to static data whose content is
|
|
overwritten by each call.
