Os driver

From Java4c

The definition of the OSAL-level-interface for user applications is not valid for driver sources.

The sources for drivers are usual written for a defined platform. The driver are an application-special part of the Hardware-adaption-layer. The same driver software need not run under another platform without changes. The driver can be tested usual only in the original platform. Therefore for the driver level the OSAL - Operation System Application Layer-interfaces are not the only one access to the hardware and the operation system. It can be used and should be used where it is possible and rational, but the driver uses specials too.
