Preprocessor Definitions

`A3D_MAKE_DATA`

  One-line macro initializer for entity data structures.

  Before calling any function, structures such as `A3DAsmModelFileData`must be initialized, either using directly A3D_INITIALIZE_DATA or using this convenience macro.

      constA3DAsmProductOccurrenceDatadata=A3D_MAKE_DATA(A3DAsmProductOccurrenceData);
      A3DAsmProductOccurrence*pPO=A3D_NULL_HANDLE;
      constA3DStatusstatus=A3DAsmProductOccurrenceCreate(&data,&pPO);

      Because this macro invokes the standard ``memset``\ function, *stdlib.h*\ must be included before this file.
