Prototype:
EdmiError edmiDeleteModelVersion(SdaiModel   modelId,
                                  SdaiVersion versionId);
Arguments:

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.
Example:
EdmiError rstat;
SdaiInteger nWrn, nErr;
SdaiRepository repId;
SdaiModel modelId;
SdaiVersion version1Id, version2Id;
SdaiModelVersion modelVersionId;
SdaiInteger myInteger;
SdaiReal myReal;
SdaiInstance instId;
SdaiAttr attrId;
SdaiPrimitiveType type;
