Using the C Wrapper in IDL Compiler Command-line Mode
The table below shows the command-line options for the
C Wrapper if the IDL Compiler is used. Default values are
underlined. Options can be valid for client and server side, see column Client
and Server.
| Option |
Client |
Server |
Value |
Description |
-DCONTEXT |
Yes |
No |
0 | 1
|
Multithreaded Client.
| 0 |
Off. The generated
client interface objects can be used in single-threaded client
environments.
|
| 1 |
On. The generated
client interface objects are thread-safe and can be used in multithreaded
client environments.
|
See Generate RPC Client for more information.
|
-DDATA_CONV_A |
Yes |
Yes |
0 | 1
|
Mapping of IDL type A fields.
| 0 |
Map IDL data type A to
the C data type unsigned char[..] without null termination (mainframe Natural,
COBOL, PL/I style).
|
| 1 |
Map IDL data type A to
C style strings
|
See Mapping Options
for more information.
|
-DDATA_CONV_NP |
Yes |
Yes |
0 | 1 |
Mapping of IDL type P, PU, N and NU fields.
| 0 |
The IDL data types are
mapped to C data type unsigned char[..] with packed or unpacked (mainframe
Natural, COBOL, PL/I style) contents.
|
| 1 |
The IDL data types are
mapped to C data type double.
|
See Mapping Options
for more information.
|
-DDATA_CONV_U |
Yes |
Yes |
0 | 1
|
Mapping of IDL type U fields.
| 0 |
Map IDL Data type U to
the C data type unsigned wchar_t[..] without null termination (mainframe

Example Generating an RPC Client
erxidl -t client.tpl -DDATA_CONV_A=1 -DDATA_CONV_U=1 example.idl
The generated C source files (client interface object and its associated
header file) will be stored in parallel to the IDL file.
Example Generating an RPC Server
erxidl -t server.tpl -DDATA_CONV_A=1 -DDATA_CONV_U=1 example.idl
The generated C source files (server interface object and its associated
header file) will be stored in parallel to the IDL file.
