edmiRemoteGetAttrsBN
EdmiError edmiRemoteGetAttrsBN(SdaiServerContext serverContextId, SdaiInstance instance, SdaiVersion version, SdaiInteger numberAttr, SdaiInvocationId *edmiInvocationId, /* [SdaiString attributeName, SdaiPrimitiveType valueType, void *value] */ ...);
Returns the value of the one or more specified attributes of an application instance. The instance is specified by its numeric instanceID that uniquely identifies it in the remote EDMdatabase. The attributer are identified by their names.
Arguments
Type | Name | Comment |
SdaiServerContext | serverContextId | Context identification, from edmiDefineServerContext |
SdaiInstance | instance | A numeric instanceID that uniquely identifies the instance of interrest in the remote EDMdatabase |
SdaiVersion | version | The version of the edmModel to apply this function call on. The <version> parameter is a numeric sequence number counting from one by increments of one for each new model version that is created. A zero model version number means the current version. |
SdaiInteger | numberAttr | The number of attributes for which to to assign values. |
SdaiInvocationId | edmiInvocationId | Currently not used. |
value | For each attribute value to read the following three arguments must be specified:
