srv_message_handler

SQL Server 2000

Calls the installed Open Data Services message handler. This function is usually used to call Microsoft® SQL Server™ from an extended stored procedure to log an error (defined by the extended stored procedure) in the SQL Server error log file or the Microsoft Windows® application log.

Syntax

int srv_message_handler (
SRV_PROC * srvproc,
int errornum,
BYTE severity,
BYTE state,
int oserrnum,
char * errtext,
int errtextlen,
char * oserrtext,
int oserrtextlen );

Arguments

srvproc

Is a pointer to the SRV_PROC structure that is the handle for a particular client connection. The srvproc parameter contains information that the ODS Library uses to manage communication and data between the application and the client.

errornum

Is an error number defined by the extended stored procedure. This number must be from 50,001 through 2,147,483,647.

severity

Is a standard SQL Server severity value for the error. This number must be from 0 through 24.

state

Is a SQL Server state value for the error.

oserrnum

Is the operating-system error number. This argument is ignored.

errtext

Is the description of the extended stored procedure error errornum.

errtextlen

Is the length of the extended stored procedure error string errtext.

oserrtext

Is the description of the operating-system error oserrnum. This argument is ignored.

oserrtextlen

Is the length of the operating-system error string oserrtext.

Returns

SUCCEED or FAIL.

Remarks

The srv_message_handler function enables an extended stored procedure to integrate with the centralized error logging and reporting features of SQL Server. SQL Server alerts can be established for events from extended stored procedures, and SQL Server Agent will monitor for these alert conditions.

If the error message is longer, it is truncated to 412 bytes.
