2022-07-22Simplify AWTEXT, AWFUN.John Ankarström
Not quite so awful anymore.
2022-07-21Simplify OnTerminate.John Ankarström
No, not "awful", AWFUN! Speaking of AWFUN, here is an alternative implementation of it: #define AWFUN(t, f) cond_fun<t, f##A, f##W> template <typename T, auto F, auto G> std::enable_if_t<std::is_same_v<T, char>, decltype(F)> cond_fun = F; template <auto F, auto G> auto cond_fun<wchar_t, F, G> = G; This implementation uses a variable template instead of a function template, but I decided against it, as (at least I think) it would instantiate useless variables that merely point to pre-existing API functions. Like, auto cond_fun__wchar_t__blablabla = MessageBoxW; auto cond_fun__char__blablabla = MessageBoxA; which is quite useless. Better to just have a constexpr function, which the compiler may inline, return the real function pointer.

2022-07-20Use GetLastError() as default for Win32Error.John Ankarström

2022-07-20Fix bug in and rename throw_nil, warn_nil.John Ankarström
In warn_nil, the return value was undefined on exception -- I think. While informative, the names throw_nil and warn_nil don't work very well in conditionals: if (warn_nil<f>(...)) g(); sounds like g should be called if f returns nil and a warning is issued. But it is actually the other way around; g is called if f is successful. if (prefer<f>(...)) g(); sounds less like that.

2022-07-19Use std::declval.John Ankarström
This is equivalent, but it may be useful to highlight that `args' does not HAVE to be declared in order to get the return type of the function call.

2022-07-19Check Windows API calls for errors more consistently.John Ankarström
Some of the checks are likely redundant, but the Windows API documentation rarely makes it clear WHICH errors may be returned (and under which circumstances) rather than simply WHETHER errors may be returned (under any circumstances, including those that do not apply in the given case).

2022-07-18Improve Library::GetProcAddress.John Ankarström
It isn't really more safe, but it removes the need for a confusing function pointer cast, which is easy to get wrong. As far as the compiler is concerned, the result is literally the same, but it does force the caller to (indirectly, via the template parameter) cast the return value, which may be a good thing.

2022-07-17Prefer f() over f(void).John Ankarström
f(void) is a C-ism that is valid but unnecessary in C++.
2022-07-17Name function arguments in headers.John Ankarström
This is obviously a lot less obtuse.
2022-07-17Add const to pointers, update spacing.John Ankarström
It seems that "right-spaced" pointers are more widely used among C++ programmers.
2022-07-17Add const to places.John Ankarström
Note that I did NOT add const to non-pointer/non-reference arguments in function declarations (without a following definition), as they do not mean anything there.
2022-07-17Remove TsmFromSz.John Ankarström
If needed in the future, it is possible to simply copy it from the Git history.

2022-07-16Rewrite TszFromSz as TsmFromSz.John Ankarström
I.e. using std::basic_string<TCHAR> instead of TCHAR *. This removes all unmanaged frees.
2022-07-15Split defs.h into separate header files.John Ankarström
This is feasible now that the makedeps script exists to automatically manage build dependencies (see 6034fe2, d00f8b3).
2022-02-15Combine header files.John Ankarström
Some older UNIX programs are organized like this, and I think it gives a very good overview over the code. See troff for an example.
