The DOS driver software is object-oriented according to C++. It is
possible to link the driver also to programs, which are written in a
different programming language. In this case you have to consider the
corresponding procedures to call these programs.
The condition for using this library is, that the compiler supports
32-bit code applications, since this library of the eGrabber-4plus is a
32-bit library.
For the memory model you have to select 32-bit-Flat. We recommend
the setting of the option ‘80386 Register Based Calling’.
For the programming of the driver, the compiler Watcom C/C++ from
Powersoft version 10.6 was used. This compiler allows the 32-bit
programming and the linking of DOS/4GW.
The driver is delivered as library (*.LIB) - file and can be linked with
all compilers, which support the used format. The header files (*.H)
are included in the user program. They provide all declarations of the
different functions, which are provided from the library.
During the start of the user program the DOS/4GW-extender must be
loaded, if the compiler does not automatically link the extender and
therefore triggers the automatic start. DOS/4GW allows the
DPMI-access, which is required for the functioning of the driver
routines.
