MI_FUNC_DESC *mi_routine_get(conn, flags, sig)

		MI_CONNECTION *conn;

		mi_integer flags;

		char *sig; 


conn
is the connection descriptor established by a previous call to mi_open() or mi_server_connect().

flags
must be 0.

sig
is the signature of the user-defined function to be looked up. The format of sig is as follows:
"[udr_type] [owner.]udr_name([arg1],...,[argN])"
In the format, udr_type is the word "function" (the default) or "procedure", and owner is the name of the routine owner. If owner is not provided, the current user name is assumed.
