Description for iowkit.dll - Code Mercenaries

IO-Warrior Dynamic Library

Code Mercenaries
IowKitGetNumDevs
Declaration:
ULONG IOWKIT_API IowKitGetNumDevs(void);
function IowKitGetNumDevs: ULONG; stdcall;
Returns the number of IO-Warrior devices present.
The function has to be called after IowKitOpenDevice() to return meaningful results.
Plugging or unplugging IO-Warriors after calling IowKitOpenDevice() is not handled. The number
IowKitGetNumDevs() returns stays the same.
Sample usage C:
IOWKIT_HANDLE ioHandle;
ULONG numDevs;
ioHandle = IowKitOpenDevice();
if (ioHandle != NULL)
{
// ... success, count devices
numDevs = IowKitGetNumDevs();
}
Sample usage Delphi:
var
ioHandle: IOWKIT_HANDLE;
numDevs: ULONG;
begin
ioHandle := IowKitOpenDevice;
if Assigned(ioHandle) then
begin
// ... success, count devices
numDevs := IowKitGetNumDevs;
end;
end;
