krb5_unparse_name_ext -  Convert krb5_principal structure to string and length. 
================================================================================

..

.. c:function:: krb5_error_code krb5_unparse_name_ext(krb5_context context, krb5_const_principal principal, char ** name, unsigned int * size)

..


:param:

	          **[in]** **context** - Library context

	          **[in]** **principal** - Principal

	          **[inout]** **name** - String representation of principal name

	          **[inout]** **size** - Size of unparsed name


..


:retval:
         -   0   Success


:return:
         -  Kerberos error codes. On failure name is set to NULL 

..







This function is similar to :c:func:`krb5_unparse_name()` , but allows the use of an existing buffer for the result. If size is not NULL, then *name* must point to either NULL or an existing buffer of at least the size pointed to by *size* . The buffer will be allocated or resized if necessary, with the new pointer stored into *name* . Whether or not the buffer is resized, the necessary space for the result, including null terminator, will be stored into *size* .



If size is NULL, this function behaves exactly as :c:func:`krb5_unparse_name()` .
