<p>The behavior of krb5_get_error_message() is only defined the first time it is called after a failed call to a krb5 function using the same context, and only when the error code passed in is the same as that returned by the krb5 function.</p>
<p>This function never returns NULL, so its result may be used unconditionally as a C string.</p>
<p>The string returned by this function must be freed using krb5_free_error_message()</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Future versions may return the same string for the second and following calls.</p>
