usb_tc08_get_last_error
short usb_tc08_get_last_error
(
short handle
)
This routine returns the last error for the unit specified by handle. If zero is passed
instead of a handle, the function returns the error associated with the last call to
usb_tc08_open_unit or usb_tc08_open_unit_async.
Note: If an invalid handle is passed to a function, the function will fail. The error code,
however, cannot be associated with a unit so usb_tc08_get_last_error will not
retain an error code in this instance. usb_tc08_get_last_error will also fail if the
invalid handle is passed to it.
The error codes, also found in the C header file, are as follows:
User/Developer error codes:
