Function dropVfoPrefix

src/core/RigctlProtocol.cpp:26–30

Drop a leading VFO token if present. Used by the split setters, which take a VFO prefix in chk_vfo=1 mode (e.g. "set_split_freq VFOB ") but resolve the TX slice themselves via findTxSlice() — so they strip the token rather than resolving it through takeVfoPrefix()/sliceForVfo().

// TX slice themselves via findTxSlice() — so they strip the token rather than
// resolving it through takeVfoPrefix()/sliceForVfo().
static void dropVfoPrefix(QStringList& parts)
{
    if (!parts.isEmpty() && isVfoName(parts.first()))
        parts.removeFirst();
}
