Function Documentation

GetFolderPath()

static OsPath GetFolderPath ( int  csidl )

static

InitLocks()

static void InitLocks ( )

static

ShutdownLocks()

static void ShutdownLocks ( )

static

StatusFromWin()

Status StatusFromWin

(

)

Returns

the Status equivalent of GetLastError(), or ERR::FAIL if there's no equivalent. SetLastError(0) should be called before the Windows function to make sure no stale errors are returned.

wutil_Allocate()

void * wutil_Allocate

(

size_t

size

)

wutil_AppWindow()

HWND wutil_AppWindow

(

)

Returns

handle to the first window owned by the current process, or 0 if none exist (e.g. it hasn't yet created one).

enumerates all top-level windows and stops if PID matches. once this function returns a non-NULL handle, it will always return that cached value.

wutil_EnableHiDPIOnWindows()

void wutil_EnableHiDPIOnWindows

(

)

wutil_Free()

void wutil_Free

(

void *

p

wutil_GetAppHDC()

void * wutil_GetAppHDC

(

)

wutil_Init()

Status wutil_Init

(

)

wutil_IsLocked()

bool wutil_IsLocked

(

WinLockId

id

)

wutil_LibModuleHandle()

HMODULE wutil_LibModuleHandle

(

)

Returns

module handle of lib code (that of the main EXE if linked statically, otherwise the DLL). this is necessary for the error dialog.
