srv_paramdata

Returns the value of a remote stored procedure call parameter.

Syntax

void * srv_paramdata (
SRV_PROC * srvproc,
int n );

where

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 the information that the ODS Library uses to manage communication and data between the Open Data Services server application and the client.

n

Indicates the number of the parameter. The first parameter is number 1.

Returns

A pointer to the parameter value. If the nth parameter is NULL, or if there is no nth parameter, or if there is no remote stored procedure, returns NULL.

Remarks

If you know the parameter name, you can use srv_paramnumber to get the parameter number. To determine whether a parameter is NULL, use srv_paramlen.

When a remote stored procedure call is made with parameters, the parameters can be passed by name or they can be passed 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. If an error occurs, the SRV_RPC handler is still called, but it appears as if there were no parameters, and srv_rpcparams returns 0.
