- debug: add provision for naming threads. allows adding current thread name to log messages and displays their names in the debugger. - replaced various if(err < 0) complain() sequences with new variants of CHECK_ERR (see lib.h) - fixes to mmgr/VC debug alloc enable code - improved h_mgr error reporting (now complains when h_free fails) - US -> UK english (partial) - fix tex_load double-free bug - move win32 mouse cursor code into sysdep - error dialog is now topmost to make sure it's visible (was a problem) - handle WM_QUIT before displaying error dialog (makes sure it's shown) also as in previous 3 revisions. This was SVN commit r2588.

this header makes available commonly used POSIX (Portable Operating System
|
|
Interface) definitions, e.g. thread, file I/O and socket APIs.
|
|
on Linux and OS X we just include the requisite headers; Win32 doesn't really
|
|
support POSIX (*), so we have to implement everything ourselves.
|
|
|
|
rationale: this is preferable to a wrapper for several reasons:
|
|
- less code (implementation is only needed on Win32)
|
|
- no lock-in (the abstraction may prevent not-designed-for operations
|
|
that the POSIX interface would have allowed)
|
|
- familiarity (many coders already know POSIX)
|
|
|
|
if a useful definition is missing, feel free to add it!
|
|
|
|
implementation reference is the "Single Unix Specification v3"
|
|
(http://www.unix.org/online.html) - it's similar to the POSIX standard
|
|
(superset?) and freely available.
|
|
|
|
|
|
* Win32 does have a POSIX subsystem (mandated by a government contract),
|
|
but it is crippled. only apps with the PE header 'subsystem' field set to
|
|
"POSIX" can use the appendant DLL, and then they can't call the regular
|
|
Windows APIs. this is obviously unacceptable - GDI is needed to set up OpenGL.
|
|
|
|
we therefore need to emulate POSIX functions using the Win32 API.
|
|
fortunately, many POSIX functions are already implemented in the VC CRT and
|
|
need only be renamed (e.g. _open, _stat).
