Header:
#include "sdai.h"
Prototype:
EdmiError edmiRemoteUnsetAggrElement(SdaiServerContext serverContextId,
                                      SdaiAggr          aggrId, 
                                      SdaiAggrIndex     index, 
                                      SdaiInvocationId  *edmiInvocationId); 
 
Arguments:

serverContextId

Context identification, from edmiDefineServerContext

aggrId

The numeric aggregateID that uniquely identifies the array for which to unset an indexed element.

index

The index of the array element to unset.

edmiInvocationId

Currently not used.

Returns:
A completion code of datatype EdmiError is the returned function value. The completion code has the following values:
Completion code = 0 : Operation successfully performed.
Completion code != 0: Error in operation. Completion code is an _EDMinterface_ error code. Use edmiGetErrorText to get the error text corresponding to the error code.
