# vendor_code

The vendor code indicates which vendor generated the kernel event. This gives every vendor a unique set of classes and subclasses to use. Use the SIOCGKEVVENDOR ioctl to look up vendor codes for vendors other than Apple. Apple uses KEV_VENDOR_APPLE.

## Declaration

```occ
u_int32_t vendor_code;
```
