# vxbW83627dhgDrvRegister( )

#### NAME

> vxbW83627dhgDrvRegister( ) - register template sensor driver

#### SYNOPSIS

void vxbW83627dhgDrvRegister(void)

#### DESCRIPTION

> This routine registers the template sensor driver with the VxBus subsystem.

> This routine contains the first instructions of the device driver that are ever executed within a VxWorks system. This function registers the driver with VxBus by providing pointers to the data structures listed previously. Once this step is complete, VxWorks is able to associate this driver with appropriate hardware within the system to form an instance.
