Parameters

undecoratedOptions

[in] Specifies a combination of flags that control what is returned. See the Remarks section for the specific values and what they do.

pRetVal

[out] Returns the undecorated name for a C++ decorated name.

Return Value

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

Note

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

The undecorateOptions can be a combination of the following flags.

Note

The flag names are not defined in the DIA SDK, so you need to either add the declarations to your code or use the raw values.
