srv_rpcparams

Returns the number of parameters for the current remote stored procedure.

Syntax

int srv_rpcparams ( SRV_PROC * srvproc );

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

Returns

The number of parameters in the remote stored procedure. If there are no parameters in the remote stored procedure or if there is not a current remote stored procedure, -1 is returned and an information error occurs.

Remarks

This function returns the number of parameters in the current remote stored procedure. It is usually called from the remote stored procedure.

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 was made with some parameters passed by name and some passed by position, an error occurs. When this error occurs, the remote stored procedure handler is called, but it does not receive the parameters and srv_rpcparams returns 0.
