How can I provide template specializations for typedefs of the same type?

Question

A 3rd party SDK defines several typedefs, e.g.:

typedef unsigned char SDK_BYTE
typedef double SDK_DOUBLE
typedef unsigned char SDK_BOOLEAN

Answer 1

Just to be complete, using the BOOST_STRONG_TYPEDEF the code could look like this:

BOOST_STRONG_TYPEDEF(SDK_BYTE, mySDK_BYTE)
BOOST_STRONG_TYPEDEF(SDK_BOOLEAN, mySDK_BOOLEAN)

template<>
mySDK_BYTE variant_cast::operator()(const SdkVariant& variant)
{
    SDK_BYTE value;
    bool res = variant.toByte(value);
    if (!res)
        diePainfully();
    return value;
}

template<>
mySDK_BOOLEAN variant_cast::operator()(const SdkVariant& variant)
{
    SDK_BOOLEAN value;
    bool res = variant.toByte(value);
    if (!res)
        diePainfully();
    return value;
}

This actually works. The only downside is, that for retrieving an SDK_BOOLEAN or SDK_BYTE one now has to write variant_cast(myVariant) or variant_cast(myVariant). Thanks Xeo.
