<p>This function reads a password from keyboard input and stores it in <em>return_pwd</em> . <em>size_return</em> should be set by the caller to the amount of storage space available in <em>return_pwd</em> ; on successful return, it will be set to the length of the password read.</p>
<blockquote>
<div><em>prompt</em> is printed to the terminal, followed by”:”, and then a password is read from the keyboard.</div></blockquote>
<p>If <em>prompt2</em> is NULL, the password is read only once. Otherwise, <em>prompt2</em> is printed to the terminal and a second password is read. If the two passwords entered are not identical, KRB5_LIBOS_BADPWDMATCH is returned.</p>
<p>Echoing is turned off when the password is read.</p>
