srv_rpcname (Extended Stored Procedure API)

重要提示：
后续版本的 Microsoft SQL Server 将删除该功能。请不要在新的开发工作中使用该功能，并尽快修改当前还在使用该功能的应用程序。 Use CLR integration instead.

Returns the procedure name component for the current remote stored procedure.

语法

DBCHAR * srv_rpcname (
SRV_PROC *
srvproc
,
int *
len 
);

Arguments

• srvproc
  Is a pointer to the SRV_PROC structure that is the handle for a particular client connection (in this case, the handle that received the remote stored procedure). The structure contains information that the Extended Stored Procedure API library uses to manage communication and data between the application and the client.

• len
  Is a pointer to an integer variable that receives the length of the database name. If len is NULL, the length of the remote stored procedure name is not returned.

Returns

A DBCHAR pointer to the null-terminated string for the remote stored procedure name component of the current remote stored procedure. If there is not a current remote stored procedure, NULL is returned and len is set to -1.

备注

This function returns only the name of the remote stored procedure. It does not include the optional specifiers for owner, database name, and remote stored procedure number.

Because it is valid to call srv_rpcname when there is not a remote stored procedure (no informational error occurs), this function provides a method for determining whether a remote stored procedure exists.

安全说明：
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.
