1.1.1.2 ! root 15: FUNCTIONS: main() - registers server as RPC server
! 16:
! 17: COMMENTS: This sample program generates a linked list to
! 18: demonstrate how the list can be transmitted over
! 19: the network more efficiently as a sized array.
! 20: The pointers are rebuilt on the server side.
! 21:
! 22: The [transmit_as] attribute (used in the typedef of
! 23: DOUBLE_LINK_TYPE in the file hello.IDL) requires the
! 24: four user-supplied functions whose names start with
! 25: the name of the presented type, DOUBLE_LINK_TYPE.
! 26:
! 27: The [in, out] attributes applied to remote procedure
! 28: parameters require the two user-supplied functions
! 29: MIDL_user_allocate and MIDL_user_free.
! 30:
! 31: The other functions are utilities that are used to
! 32: build or display the data structures.
