RSE equivalent of VDEOpen with the ADEOP_FIELD opcode This API will return the same information as VDEOpen with the same input but it will get the information from a socket to the specified port that is communicating through RSE. The RSE server is assumed to be running on the same machine. If there is a problem communicating with the target port, ADERC_SYS_ERR will be returned, otherwise the return code will be match that of VDEOpen with the same inputs. The protocol for this particular request is: SEND: enum RSE_OPEN_FIELD ALIAS server_alias - 10 char name of CODE server followed by terminating null ULONG ade_options - an unsigned long containing bit flags, indicating which options have been selected. FDIN target_field - the FDIN struct will be streamed out character by character. typedef struct { CHAR library[11]; // Data base library name CHAR file[11]; // Data base file name CHAR record[11]; // Data base record name CHAR field[11]; // Data base field name CHAR valCheck; // Data base validity check } FDIN; RECEIVE: LONG return_code ADE_CB control_block_ptr - this char * is just a handle, it can never be dereferenced FDOUT ref_field_info - the FDOUT struct will be streamed in and stuffed directly into the C structure.

The protocol for this particular request is: SEND: enum RSE_READ_FIELD ADE_CB control_block_ptr - this char * is just the handle that was returned from the previous RSEOpenXXX() call. RECEIVE: LONG return_code USHORT length - the number of bytes in the subsequent buffer CHAR[] buffer - the data that is waiting for this read, the data will vary depending on the open operation preceeding the read. Since the open operation was ADEOP_FIELD the buffer will contain a FDKWD struct, followed optionally by the parameter string. typedef struct { SHORT length; // Length of keyword parameters SHORT numParameter; // number of parameters SHORT id; // keyword identifier // List of keyword parameters } FDKWD; The parameter string contains numParameter parameters, each delimited with a null character and is contained in the length bytes following the FDKWD struct in the buffer. Return Codes: ADERC_OK = successful completion ADERC_COMM_ERR = communication error ADERC_SYS_ERR = local system error ADERC_EOF = end of file/list/data Return codes not supported (yet): ADERC_INVALID_ALIAS = server alias not active ADERC_BAD_SEQUENCE = invalid call sequence ADERC_PROG_ERR = programming error
