NAME

getpass() − read a password

SYNOPSIS

#include <unistd.h>

char *getpass(const 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 terminates input and sends 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, more than might be expected, the size of programs not otherwise using standard I/O. 

WARNINGS

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

STANDARDS CONFORMANCE

getpass(): AES, SVID2, XPG2, XPG3, XPG4
