Installable
Drive Module-Definition File
The
module-definition (.DEF) file of an installable driver names the driver,
exports the DriverProc
function, and defines a driver description. The following example shows a
typical module-definition file for an installable driver:
LIBRARY OSCI
DESCRIPTION 'FREQ,AMPL:Oscilloscope frequency and
amplitude drivers.'
EXPORTS
DriverProc
Some
installation applications may open the driver and retrieve the description line
to use when installing the driver. To remain compatible with these installation
applications, the description line should have this form:
DESCRIPTION alias[,alias]...:text
The alias
specifies a unique name for the driver that applications can use to open the
driver. The alias also serves as the value name associated with the driver in
the registry. Multiple aliases are separated by commas. The text
describes the purpose of the driver.
