edmiRemoteGetOpenMode

EdmiError edmiRemoteGetOpenMode(SdaiServerContext serverContextId,
                                  SdaiInstance      currInst, 
                                  SdaiAccessMode    *openMode,
                                  SdaiInvocationId  *edmiInvocationId);

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
SdaiInstance	currInst	A modelId or repositoryId that uniquely identifies a model or a repository within the EDMdatabase . This is the repository or model for which to get the current open mode.
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
