FAX_DEVICE_STATUSA structure (winfax.h)
The FAX_DEVICE_STATUS structure contains information about the current status of a fax device. In addition to the status, the structure also includes data on whether the device is currently sending or receiving a fax transmission, device and station identifiers, sender and recipient names, and routing information.

Members
SizeOfStruct
Type: DWORD
Specifies the size, in bytes, of the FAX_DEVICE_STATUS structure. The fax service sets this member to sizeof(FAX_DEVICE_STATUS).
CallerId
Type: LPCTSTR
If the JobType member is equal to the JT_RECEIVE job type, CallerId is a pointer to a null-terminated character string that identifies the calling device that sent the active fax document. This string can include the telephone number of the calling device.
Csid
Type: LPCTSTR
Pointer to a constant null-terminated character string that specifies the called station identifier of the device.
CurrentPage
Type: DWORD
Specifies a DWORD variable that indicates the number of the page in the fax transmission that the fax device is currently sending or receiving. The page count is relative to one.
DeviceId
Type: DWORD
Specifies a DWORD variable that indicates the permanent line identifier for the fax device of interest.
DeviceName
Type: LPCTSTR
Pointer to a constant null-terminated character string that specifies the name of the fax device of interest.
DocumentName
Type: LPCTSTR
Pointer to a constant null-terminated character string to associate with the fax document that the device is currently sending or receiving. This is the user-friendly name that appears in the print spooler.
JobType
Type: DWORD
Specifies a DWORD variable that identifies the type of fax job that is currently active on the device. This member can be one of the following job types.
JT_SEND
The fax device is sending a fax document.
JT_RECEIVE
The fax device is receiving a fax document.
JT_UNKNOWN
The fax device is in an unknown or idle state.
PhoneNumber
Type: LPCTSTR
If the JobType member is equal to the JT_SEND job type, PhoneNumber is a pointer to a constant null-terminated character string that is the fax number dialed for the outgoing fax transmission.
RoutingString
Type: LPCTSTR
If the JobType member is equal to the JT_RECEIVE job type, RoutingString is a pointer to a constant null-terminated character string that specifies the routing string for an incoming fax. The string must be of the form:
Canonical-Phone-Number[|Additional-Routing-Info]
where Canonical-Phone-Number
is defined in the Address topic of the TAPI documentation (see the Canonical Address subheading); and Additional-Routing-Info
is the subaddress of a Canonical Address, and uses the subaddress format.
SenderName
Type: LPCTSTR
Pointer to a constant null-terminated character string that specifies the name of the sender who initiated the fax transmission.
RecipientName
Type: LPCTSTR
Pointer to a constant null-terminated character string that specifies the name of the recipient of the fax transmission.
Size
Type: DWORD
Specifies a DWORD variable that indicates the size, in bytes, of the active fax document.
StartTime
Type: FILETIME
Specifies a FILETIME structure that contains the starting time of the current fax job expressed in UTC.
Status
Type: DWORD
Specifies a DWORD variable that is a fax device status code or value. This member can be one of the predefined device status codes shown following.
FPS_DIALING
The device is dialing a fax number.
FPS_SENDING
The device is sending a fax document.
FPS_RECEIVING
The device is receiving a fax document.
FPS_COMPLETED
The device has completed sending or receiving a fax transmission.
FPS_UNAVAILABLE
The device is not available because it is in use by another application.
FPS_BUSY
The device has encountered a busy signal.
FPS_NO_ANSWER
The receiving device did not answer the call.
FPS_BAD_ADDRESS
The device dialed an invalid fax number.
FPS_NO_DIAL_TONE
The sending device cannot complete the call because it does not detect a dial tone.
FPS_DISCONNECTED
The fax call was disconnected by the sender or the caller.
FPS_FATAL_ERROR
The device encountered a fatal protocol error.
FPS_NOT_FAX_CALL
The device has received a data call or a voice call.
FPS_CALL_DELAYED
The device delayed a fax call because the sending device received a busy signal multiple times. The device cannot retry the call because dialing restrictions exist. (Some countries/regions restrict the number of retry attempts when a number is busy.)
FPS_CALL_BLACKLISTED
The device could not complete a call because the telephone number was blocked or reserved; numbers such as 911 are blocked.
FPS_INITIALIZING
The device is initializing a call.
FPS_OFFLINE
The device is offline and unavailable.
FPS_RINGING
The device is ringing.
FPS_AVAILABLE
The device is available.
FPS_ABORTING
The device is aborting a fax job.
FPS_ROUTING
The device is routing a received fax document.
FPS_ANSWERED
The device answered a new call.
FPS_HANDLED
The fax service processed the outbound fax document; the fax service provider will transmit the document.
StatusString
Type: LPCTSTR
This member must be NULL.
SubmittedTime
Type: FILETIME
Specifies a FILETIME structure that contains the time the client submitted the fax document for transmission to the fax job queue. The time is expressed in UTC.
TotalPages
Type: DWORD
Specifies a DWORD variable that indicates the total number of pages in the fax transmission.
Tsid
Type: LPCTSTR
Pointer to a constant null-terminated character string that specifies the transmitting station identifier (TSID). This identifier is usually a telephone number.
UserName
Type: LPCTSTR
Pointer to a constant null-terminated character string that specifies the name of the user who submitted the active fax job.
Remarks
The fax client application can call the FaxGetDeviceStatus function to retrieve status information for the fax device of interest. The function returns the information in a FAX_DEVICE_STATUS structure.
For more information, see Fax Device Management. For information about the status information a fax service provider supplies for an active fax operation, see the FAX_DEV_STATUS topic.
Note
The winfax.h header defines FAX_DEVICE_STATUS as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
