ProUnitsystemUnitGet

[dschmitz]

Hello all,

I have a "strange" problem (one of many actually). But the one I'd like help with is this: I get blown out of Pro/E WF2 when the function ProUnitsystemUnitGet is called and I can't seem to get the return value. The code is below. When I comment out the ProUnitsystemUnitGet, the program works fine. Any thoughts? TIA. -Dave Schmitz, Ingenium Product Development

int ReadData(ProMdl *ModelHandle))
{
ProError tkerr;
ProUnitsystem UnitSystem;
ProUnititem wLengthUnit;

tkerr = ProMdlPrincipalunitsystemGet(ModelHandle, &UnitSystem);
tkerr = ProUnitsystemUnitGet(&UnitSystem, PRO_UNITTYPE_LENGTH, &wLengthUnit);
}

Thanks to Patrick, Michael and William for responding. My issue was with the ModelHandle passed to the routine. The routine header should not have been a pointer, reading:

int ReadData(ProMdl ModelHandle)
{
ProError tkerr;
ProUnitsystem UnitSystem;
ProUnititem wLengthUnit;

tkerr = ProMdlPrincipalunitsystemGet(ModelHandle, &UnitSystem);
tkerr = ProUnitsystemUnitGet(&UnitSystem, PRO_UNITTYPE_LENGTH, &wLengthUnit);
}
