Returns the current open mode of a model or repository within a locally connected database. This feature has been implemented to provide all EDMInterface functionality through the remote EDMInterface calls. Only applicable for the LOCAL_CONTEXT communication type.

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiString	repositoryName	If the argument <modelName> is NULL or an empty string, this is the name of the data repository for which to change its open mode. Otherwise, this is the name of the repository that contains the model for which to change its open mode. Repository names are case sensitive
SdaiString	modelName	The name of the model for which to change its open mode. Model names are case sensitive. If this argument is NULL or an empty string, this operation will change the open mode of the repository <repositoryName>
SdaiAccessMode	openMode	A variable that will receive the current access mode to the model or repository. Possible access modes are sdaiRO, sdaiRW and sdaiNOACCESS.
SdaiInvocationId	edmiInvocationId	Currently not used.

Return Value
