====== Server API ======

API that can enable server matching or controls the device from the BioStar application. \\
<callout type="warning" icon="true"><WRAP em>Warning</WRAP> \\
Due to the issues with the management of UFMatcher.dll which was provided by a separate independent Corporation,​ Runnable examples will not be available anymore. \\ 
Please reference the prior examples at the code level only. ​\\ \\ 
Other technical supports including fingerprint libraries for server matching can be provided by Xperix. \\

  * [[BS2_SetServerMatchingHandler]]: Registers the server matching handler.
  * [[BS2_VerifyUser]]: Transfers user information mapped to the card or user ID authentication results to the device.
  * [[BS2_IdentifyUser]]: Transfers user information mapped to the fingerprint authentication results to the device.
  * [[BS2_VerifyUserEx]]: [+ 2.4.0] Transfers user information mapped to the card or user ID authentication results to the device. 
  * [[BS2_IdentifyUserEx]]: [+ 2.4.0] Transfers user information mapped to the fingerprint authentication results to the device. 
  * [[BS2_VerifyUserSmall]]: [+ 2.6.3] Transfers user information mapped to the card or user ID authentication results to the device.
  * [[BS2_IdentifyUserSmall]]: [+ 2.6.3] Transfers user information mapped to the fingerprint authentication results to the device.
  * [[BS2_VerifyUserSmallEx]]: [+ 2.6.3] Transfers user information mapped to the card or user ID authentication results to the device.
  * [[BS2_IdentifyUserSmallEx]]: [+ 2.6.3] Transfers user information mapped to the fingerprint authentication results to the device.
  * [[BS2_VerifyUserFaceEx]]: [+ 2.7.2] Transfers user information mapped to the card or user ID authentication results to the device.
  * [[BS2_SetUserPhraseHandler]]:​ [+ 2.7.0] Registers the server user phrase handler.
  * [[BS2_ResponseUserPhrase]]:​ [+ 2.7.0] Transfers the user phrase to the device.
  * [[BS2_SetBarcodeScanListener]]: [+2.8.2] Register the listener function that detects barcode input.
  * [[BS2_SetOsdpStandardDeviceStatusListener]]: [+ 2.9.1] Register a listener function that detects state changes of the OSDP device.
===== Callback Function ======
<code cpp>
typedef void (*OnVerifyUser)(uint32_t deviceId, uint16_t seq, uint8_t isCard, uint8_t cardType, const uint8_t* data, uint32_t dataLen);
typedef void (*OnIdentifyUser)(uint32_t deviceId, uint16_t seq, uint8_t format, const uint8_t* templateData, uint32_t templateSize);
</code>
1. //OnVerifyUser// \\ 
Callback function that is called when the BioStar application needs to distinguish whether the card or user ID matches. \\ \\  
2. //OnIdentifyUser// \\ 
Callback function that is called when the BioStar application needs to distinguish whether the fingerprint matches. \\ 

\\

==== OnUserPhrase ====
Callback function asking for user phrase to the server.
<code cpp>
typedef void (*OnUserPhrase)(uint32_t deviceId, uint16_t seq, const char* userID);
</code>
\\

1. //deviceId// \\ 
Device ID  \\ \\ 
2. //seq// \\ 
Packet sequence  \\ \\ 
3. //userID// \\ 
User ID  \\ \\ 

==== OnBarcodeScanned ====
Callback function called when barcode is scanned on the device. \\ \\ 
<code cpp>
typedef void (*OnBarcodeScanned)(uint32_t deviceId, const char* barcode);
</code>
\\
1. //deviceId// \\ 
Device ID that sent the scanned barcode.  \\ \\ 
2. //barcode// \\ 
Barcode string read from device.  \\ \\ 


==== OnOsdpStandardDeviceStatusChanged ====
This is a callback function that is called when the state of the OSDP device changes.  \\ \\ 
<code cpp>
typedef void (*OnOsdpStandardDeviceStatusChanged)(uint32_t deviceId, const BS2OsdpStandardDeviceNotify* notifyData);
</code>
\\
1. //deviceId// \\ 
OSDP device identifier.  \\ \\ 
2. //notifyData// \\ 
OSDP device information.  \\ \\
