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. 

BUGS

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