getpass(3C)                       SDK R4.11                      getpass(3C)


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 will terminate
       input and send an interrupt signal to the calling program before
       returning.

   Files
       /dev/tty
