ObjFW  History of src/OFStdIOStream_Win32Console.m of 14dcc4929af72b04

Previously, this just assumed the existance of file descriptors 0, 1 and
2 - however, in GUI applications on Windows, these were missing when not
started from a console. file: [7e7d715431] check-in: [0f8a72d43c] user: js, branch: trunk, size: 8746 [annotate] [blame] [check-ins using] [diff]

There is no reliable way to check if C++ already defined those, as Clang
now defines char{16,32}_t even when it is not in C++ 11 mode. So we
cannot check if we are not in C++ 11 and then define them and otherwise
rely on the C++ 11 types. file: [24ecc550f0] check-in: [505137f25f] user: js, branch: trunk, size: 8694 [annotate] [blame] [check-ins using] [diff]

This allows retrieving the number of bytes already written before the
write failed, allowing to retry without writing data that has already
been written. file: [451d779be8] check-in: [2ae01218ef] user: js, branch: trunk, size: 8471 [annotate] [blame] [check-ins using] [diff]

This removes several initializers that omitted the errNo. Removing those
forces to think about whether there is a meaningful errNo to set instead
of just omitting it. file: [e75a0d88c9] check-in: [4f36894ce7] user: js, branch: trunk, size: 8084 [annotate] [blame] [check-ins using] [diff]

This matches Apple's style. file: [b94d48eb9c] check-in: [6b77a5dd8b] user: js, branch: trunk, size: 8011 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [7f3fc13f71] check-in: [4af49a13c3] user: js, branch: trunk, size: 8029 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [b6e40ac9ff] check-in: [44f45c2e35] user: js, branch: trunk, size: 8026 [annotate] [blame] [check-ins using] [diff]

U+FFFD is for unrepresentable characters, not U+FFFE. file: [c7b07d3dc1] check-in: [9d70e660ea] user: js, branch: trunk, size: 7841 [annotate] [blame] [check-ins using] [diff]

When writing an incomplete surrogate, it now writes everything up to
that incomplete surrogate, remembers the incomplete surrogate and writes
it as soon as the surrogate is completed by a following write. file: [c806288ec6] check-in: [3a0fdb6701] user: js, branch: trunk, size: 7841 [annotate] [blame] [check-ins using] [diff]

It now returns <= 0 on error, with negative values being the number of
bytes it would have needed * -1.

This can be used to detect cut off and how many bytes are missing. file: [f55d77f8b8] check-in: [5e2ef97c35] user: js, branch: trunk, size: 6293 [annotate] [blame] [check-ins using] [diff]

On reads, surrogates that have been cut off are now properly handled. file: [88dea4ced5] check-in: [566d4df603] user: js, branch: trunk, size: 6260 [annotate] [blame] [check-ins using] [diff]

The previous way was to set the codepage to UTF-8, however, this does
not work properly on some versions of Windows.

Instead, this catches reads / writes on of_std* on the lowlevel,
interprets it as UTF-8, converts it to / from UTF-16 and then uses
ReadConsoleW() / WriteConsoleW().

Surrogates being cut in the middle is not properly handled yet, this
will be implemented in a follow up commit. file: [7d8639b924] check-in: [3e1b6bccbc] user: js, branch: trunk, size: 5464 [annotate] [blame] [check-ins using]
