This function reads a password from keyboard input and stores it in return_pwd . size_return should be set by the caller to the amount of storage space available in return_pwd ; on successful return, it will be set to the length of the password read.

prompt is printed to the terminal, followed by”:”, and then a password is read from the keyboard.

If prompt2 is NULL, the password is read only once. Otherwise, prompt2 is printed to the terminal and a second password is read. If the two passwords entered are not identical, KRB5_LIBOS_BADPWDMATCH is returned.

Echoing is turned off when the password is read.
