srv_wsendmsg (Extended Stored Procedure API)

Important :
Cette fonctionnalité sera supprimée dans une prochaine version de Microsoft SQL Server. Évitez d'utiliser cette fonctionnalité dans de nouveaux travaux de développement, et modifiez dès que possible les applications qui utilisent actuellement cette fonctionnalité. Use CLR integration instead.

Sends a Unicode message to the client.

Syntaxe

int srv_wsendmsg(SRV_PROC * 
srvproc
, int 
msgnum
, int 
severity
, WCHAR * 
message
, int 
msglen
);

Arguments

• srvproc
  Is a pointer to the SRV_PROC structure that is the handle for a particular client connection. The structure contains information the Extended Stored Procedure API library uses to manage communication and data between the application and the client.

• Msgnum
  Is a 4-byte message number.

• Severity
  Specifies the severity of the error. A severity less than or equal to 10 is considered an informational message; otherwise, it is an error.

• message
  Is a pointer to a Unicode string to be sent to the client.

• msglen
  Specifies the length, in characters, of message.

Returns

SUCCEED or FAIL.

Notes

Use this function to send messages in Unicode. It is similar to srv_sendmsg, but the message it sends is a WCHAR string rather than type DBCHAR string. Note that message length is reported in characters rather than bytes, and msglen will never be equal to SRV_NULLTERM.

The function returns FAIL when

• The msglen given is not in the range of 0-32242.
• The msglen given is 0 but the message pointer is NULL.
• There is error when sending the error message through network.

Remarque relative à la sécurité :
You should thoroughly review the source code of extended stored procedures, and you should test the compiled DLLs before you install them on a production server. For information about security review and testing, see this Microsoft Web site.
