IDiaSymbol::get_numericProperties

  • Article

Retrieves the set of numeric properties for this symbol.

Syntax

HRESULT get_numericProperties(
    DWORD cnt,
    DWORD *pcnt,
    DWORD *pProperties
);

Parameters

cnt

[in] The number of DWORDs pointed to by the buffer pProperties.

pcnt

[out] Returns the number of valid properties set in pProperties.

pProperties

[out] Returns the set of properties for this symbol.

Return Value

If successful, returns S_OK; otherwise, returns S_FALSE or an error code.

Note

A return value of S_FALSE means that the property is not available for the symbol.

Example

CComPtr<pSymbol> pSymbol;
BOOL f = FALSE;
HRESULT hr = E_FAIL;
...

hr = pSymbol->get_isHLSLData(&f);
if (FAILED(hr)) {
    return hr;
}
if (f) {
    DWORD value = 0;
    hr = pSymbol->get_numberOfRegisterIndices(&value);
    if (hr == S_OK && value > 0) {
        DWORD *pOff = new (std::nothrow) DWORD[value];
        if (pOff == NULL) {
            return E_OUTOFMEMORY;
        }
        DWORD propertiesRead;
        if (IfOkOrReportAuto(pSymbol->get_numericProperties(value, &propertiesRead, pOff))) {
            value = __min(value, propertiesRead);
            for (DWORD i = 0; i < value; i++) {
                printf("%u\n", pOff[i]);
            }
        }
        delete[] pOff;
    }
}
