/* This file may be used in three place. That is vbox_tmpl.c,
 * vbox_common.c and vbox_driver.c. The vboxUniformedAPI and some
 * types used for vboxUniformedAPI is defined here.
 *
 * The vbox_tmpl.c is the only place where the driver knows the inside
 * architecture of those vbox structs(vboxObj, vboxSession,
 * pFuncs, vboxCallback and vboxQueue). The file should be included
 * after the currect vbox_CAPI_v*.h, then we can use the vbox structs
 * in vboxGlobalData. The vbox_tmpl.c should implement functions
 * defined in vboxUniformedAPI.
 *
 * In vbox_driver.c, it is used to define the struct vboxUniformedAPI.
 * The vbox_driver.c collects vboxUniformedAPI for all versions.
 * Then vboxRegister calls the vboxRegisterUniformedAPI to register.
 * Note: In vbox_driver.c, the vbox structs in vboxGlobalData is
 * defined by vbox_CAPI_v2.2.h.
 *
 * The vbox_common.c, it is used to generate common codes for all vbox
 * versions. Bacause the same member varible's offset in a vbox struct
 * may change between different vbox versions. The vbox_common.c
 * shouldn't directly use struct's member varibles defined in
 * vbox_CAPI_v*.h. To make things safety, we include the
 * vbox_common.h in vbox_common.c. In this case, we treat structs
 * defined by vbox as a void*. The common codes don't concern about
 * the inside of this structs(actually, we can't, in the common level).
 * With the help of vboxUniformed API, we call VirtualBox's API and
 * implement the vbox driver in a high level.
 *
 * In conclusion:
 *  * In vbox_tmpl.c, this file is included after vbox_CAPI_v*.h
 *  * In vbox_driver.c, this file is included after vbox_glue.h
 *  * In vbox_common.c, this file is included after vbox_common.h
