EdmiError edmiRemoteGetAttrPrimitiveType(SdaiServerContext serverContextId,
SdaiAttr attributeId,
SdaiPrimitiveType *dataType,
SdaiInvocationId *edmiInvocationId);
Returns the required primitive type of the data values to be assigned to a specified attribute.
Arguments
| Type | Name | Comment |
| SdaiServerContext | serverContextId | Context identification, from edmiDefineServerContext |
SdaiAttr | attributeId | The numeric attributeID that uniquely identifies the attribute definition instance in the EDMdatabase. AttributeIds are returned from the functions edmiRemoteGetAttrDefinition and edmiRemoteGetAttrDefinitionBN. |
| SdaiPrimitiveType | dataType | A variable that will receive the required primitive type of the data values that may be assigned to the attribute. |
| SdaiInvocationId | edmiInvocationId | Currently not used. |
Return Value
