HANDLE m_handle = 0;

CCyUSBDevice *USBdevList = new CCyUSBDevice((HANDLE)0,CYUSBDRV_GUID,true);

Tip
The handles are internally managed by CyAPI.lib and there is no need to expose them to the user.

!=0;

In the code, it is possible to call

TE_USB_FX2_Open(

USBdevList, 1)!=0

) where TE0300_

Close

Open(

&m_handle);

) is used.

Note
When a new handle to the device driver is open (

TE_USB_FX2_

Close(USBdevList);The

Open() run successfully) other internal handles (inside USBDeviceList) are automatically closed by TE_USB_FX2_

Close

Open() function

takes an already initialized USB device list (USBDeviceList) and closes the handle to the Trenz Electronic device driver, if one is open. This function closes all internal handles of USBDeviceList.

TE0300_SendCommand(handle, cmd, cmd_length, reply, &reply_length, timeout)

. No more than one handle can be active on the same time. It is a behavior inherithed by CyAPI.dll Open() function. For this reason, TE_USB_FX2_

SendCommand(USBdevList, cmd, cmd_length, reply, reply_length, timeout)

Close() function is almost useless.

TE_USB_FX2_Open()

TE_USB_FX2_Open(USBdevList, x) acts more as a SelectCard() function because the list

...

of USB devices is already created in USBdevList.

USBdevList);

Tip
This function closes all internal handles of USBDeviceList.

This function does not differ much from from its homonym of the previous TE0300DLL.dll; the only difference is that this function closes a handle (like TE0300DLL.dll) to the driver but the handle is not exposed to user because it is not exposed by USBDeviceList (unlike TE0300DLL.dll).

...

In the code, it is possible to call TE_USB_FX2_

...

Close() where TE0300_Close() is used, but

...

it is rare that you would ever need to call TE_USB_FX2_Close() explicitly (though doing so would not cause any problems).

...

TE_USB_FX2_Open() realize automatically much of the TE_USB_FX2_Close() work.

...

Close is automatically carried out by the TE_USB_FX2_Open() function

...

, if another handle to the same device driver is already open (i.e. a TE_USB_FX2_Open() has been successfully used before).

...

Note

title	Warning about derived variables

...

If TE_USB_FX2_Close() is called, then dynamically allocated members of the CCyUSBDevice class are de-allocated. And, all "shortcut" pointers to elements of the EndPoints array (ControlEndPt, IsocIn/OutEndPt, BulkIn/OutEndPt, InterruptIn/OutEndPt) are reset to NULL.
