-keep file_types
Specifies which files to retain. To produce the object modules, the IDL compiler first creates C source modules, then invokes the target C compiler to produce object modules, and finally, deletes the C source modules. If you do not use -keep, only the object modules are saved.
The file types are as follows:
| none | Does not save the C source or the object modules. Does not invoke the C compiler. |
| c_source | Saves only the C source modules. Does not invoke the C compiler. |
| object | Saves only the object modules. |
| all | Saves both the C source and the object modules. |
