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 krb5_free_principal() to free allocated memory for principal when it is no longer needed.

Beginning with release 1.20, the name type of the principal will be inferred as KRB5_NT_SRV_INST or KRB5_NT_WELLKNOWN based on the principal name. The type will be KRB5_NT_PRINCIPAL if a type cannot be inferred.
