# set\_processor\_type

```
Set target processor type.
Once a processor module is loaded, it cannot be replaced until we close the idb.
     processor - name of processor in short form.
     level     - the request level:
 SETPROC_IDB         set processor type for old idb
 SETPROC_LOADER      set processor type for new idb;
                     if the user has specified a compatible processor,
                     return success without changing it.
                     if failure, call loader_failure()
 SETPROC_LOADER_NON_FATAL the same as SETPROC_LOADER but non-fatal failures.
 SETPROC_USER        set user-specified processor
                     used for -p and manual processor change at later time

success set_processor_type(string processor, long level);

#define SETPROC_IDB              0
#define SETPROC_LOADER           1
#define SETPROC_LOADER_NON_FATAL 2
#define SETPROC_USER             3
