Returns the number of a remote stored procedure call parameter.
Syntax
int srv_paramnumber (
SRV_PROC *
srvproc
,
DBCHAR *
name
,
int
namelen
);
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 call). The structure contains information the Extended Stored Procedure API library uses to manage communication and data between the application and the client.
- name
Is a pointer to the parameter name.
- namelen
Is the length of name. If name is null-terminated, set namelen to SRV_NULLTERM.
Returns
The parameter number of the named parameter. The first parameter is 1. If there is no parameter named name or no remote stored procedure, 0 is returned and a message is generated.
Hinweise
When a remote stored procedure call is made with parameters, the parameters can be passed either by name or by position (unnamed). If the remote stored procedure call is made with some parameters passed by name and some passed by position, an error occurs. The SRV_RPC handler is still called, but it appears as if there were no parameters, and srv_rpcparams returns 0.

| 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. |
