The address of the default XDR routine to call if the dscmp argument is not found in the choices array.
A filter primitive that translates between a discriminated union and its corresponding external representation. The xdr_union routine first translates the discriminant of the union located at dscmp . This discriminant is always of type enum_t .Next, the routine translates the union data located at unp . To translate the union data the xdr_union routine first searches the structure pointed to by the choices argument for the union discriminant passed in the dscmp argument. If a match is found, the xdr_union routine calls proc to translate the union data.
The end of the xdr_discrim structure array must contain an entry with the value NULL for proc . If the xdr_union routine reaches this entry before finding a match, the routine calls the default procedure (if it is not NULL ).
TRUE Indicates success. FALSE Indicates failure.
