srv_paramtype

Returns the datatype of a remote stored procedure call parameter.

Syntax

int srv_paramtype (
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 1.

Returns

A token value for the datatype of the parameter. A readable description for the value is available using srv_symbol. For a list of datatypes, see Datatypes. If there is no nth parameter or if there is no remote stored procedure, returns - 1.

Remarks

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.
