<p>This function creates a principal from a length-counted string and a variable-length list of length-counted components. The list of components ends with the first 0 length argument (so it is not possible to specify an empty component with this function). Call <a class="reference internal" href="krb5_free_principal.html#c.krb5_free_principal" title="krb5_free_principal"><tt class="xref c c-func docutils literal"><span class="pre">krb5_free_principal()</span></tt></a> to free allocated memory for principal when it is no longer needed.</p>
