5.3 Software Driver Naming Convention
The functions of PCI-7200's software drivers are using full-names to
represent the functions' real meaning. The naming convention rules
are :
Ÿ DOS
_{hardware_model}_{action_name}. e.g. _7200_Initial ().
Ÿ Windows 95/98
In order to recognize the difference between DOS library and
Windows library, A capital "W" is put on the head of each
function name of the Windows DLL driver. e.g. W_7200_Initial ()
There are 21 function calls provided by each driver for PCI-7200
Digital I/O cards; all drivers (DOS, Win-95/98) provide the same
function capability. The function names using in Windows is only a
capital "W" put on the head of each function name of DOS library.
The detailed descriptions of each function are specified in the
following sections.
5.4 _7200_Initial
@ Description
A PCI-7200 card is initialized according to the card number.
Because the PCI-7200 is PCI bus architecture and meets the plug
and play design, the IRQ and base_address ( pass-through
address) are assigned by system BIOS directly. Every PCI-7200 card
has to be initialized by this function before calling other functions.
