srv_paramsetoutput (Extended Stored Procedure API)

Important note Important

This feature will be removed in a future version of Microsoft SQL Server. Do not use this feature in new development work, and modify applications that currently use this feature as soon as possible. Use CLR integration instead.

Sets the value of a return parameter. This function supersedes the srv_paramset function.


int srv_paramsetoutput ( 
SRV_PROC * 
srvproc 
, 
int 
n 
, 
BYTE * 
pbData 
, 
ULONG  
cbLen 
, 
BOOL 
fNull  
);

srvproc

Is a handle for a client connection.

n

Is the ordinal number of the parameter to be set. The first parameter is 1.

pbData

Is a pointer to the data value to be sent back to the client as a procedure return parameter.

cbLen

Is the actual length of the data to be returned. If the data type of the parameter specifies values of a constant length and does not allow null values (for example, srvbit or srvint1), cbLen is ignored. A value of 0 signifies zero-length data if fNull is FALSE.

fNull

Is a flag indicating whether the value of the return parameter is NULL. Set this flag to TRUE if the parameter should be set to NULL. The default value is FALSE. If fNull is set to TRUE, cbLen should be set to 0 or the function will fail.

If the parameter information was successfully set, SUCCEED is returned; otherwise, FAIL. FAIL is returned when

  • the parameter is not a return parameter, or

  • the cbLen argument is invalid.

Security Note   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.
