SECTION 9 APPLICATION COMMAND INTERFACE PROGRAMMING GUIDE
2-9
ACI_E_OPEN_CCB_ALREADY_IN_USE:
An attempt to establish a logical connection to a physical device is refused by the Application
Command Interface due to the fact that the Command Control Buffer is already used for a logical
connection to a device.
ACI_E_OPEN_ILLEGAL_INQUIRY_MODE:
An illegal inquiry mode has been specified. Probably, an invalid major or minor interrupt number,
or an illegal Interrupt Request Level has been specified, or an illegal Exception Vector Number
has been specified. The value is also returned when the data within the inquiry mode are not
consistent. For example, if the MAILBOX mode is specified but one or more of the most significant
16 bits are set.
ACI_E_OPEN_ILLEGAL_RESPONSE_MODE:
An illegal response mode has been specified. Probably, an invalid major or minor interrupt
number, or an illegal Interrupt Request Level has been specified, or an illegal Exception Vector
Number has been specified. The value is also returned when the data within the response mode
are not consistent. For example, if the MAILBOX mode is specified but one or more of the most
significant 16 bits are set.
ACI_E_OPEN_ILLEGAL_DATA_EXCHANGE_MODE:
An illegal data exchange mode has been specified. This status is returned whenever one or
more of the least significant 30 bits are set.
ACI_E_OPEN_ILLEGAL_LOGICAL_DEVICE_NUMBER:
An illegal logical device number has been specified which cannot be translated to its
corresponding physical device code by the Application Command Interface.
ACI_E_OPEN_INSUFFICIENT_CCBS:
The Application Command Interface is not able to allocate a Command Control Buffer within its
internal Command Control Buffer list.
ACI_E_OPEN_DEVICE_ALREADY_IN_USE:
Another application already owns the physical device and no other can gain the ownership of this
device until the certain application releases the logical connection to the device.
ACI_E_OPEN_INSUFFICIENT_MEMORY:
The Application Command Interface cannot allocate the memory required by a device driver when
the device driver has to be activated upon the receipt of an OPEN.
ACI_E_OPEN_CANNOT_ACTIVATE_DEVICE_DRIVER:
The Application Command Interface cannot activate the device driver dealing with the physical
device.
