The RegGetValue API is a C-interface API and as such it signals error conditions to the caller using return codes. In particular, this function returns a value of type LONG: ERROR_SUCCESS (that is, zero) in the case of success and a different value in the case of errors. For example...
If the incompatible changes do have an impact for you, you can set the new system variable terminology_use_previous to BEFORE_8_0_26 to make MySQL Server use the old versions of the names for the objects specified in the previous list. This enables monitoring tools that rely on the old ...
In yet further embodiments, a flare is provided near the tip of the pointer in order to reduce the force required by fingers of the user to manipulate and hold the pointer.Fleck, David CRawlings, ScottPollmann, Konrad WHipprn, Jan
The error which MSVC gives for this looks like: error C2662: ‘void oh_no::non_const(void)’: cannot convert ‘this’ pointer from ‘const oh_no’ to ‘oh_no &’ So it’s trying to pass a const oh_no as the implicit object parameter to non_const, which doesn’t work. But whe...
