Windows GDI declarations for pixel-format selection, pixel-format installation, and buffer swapping on one device context.
Descriptor schema passed to pixel-format selection and installation functions.
nSize and nVersion: descriptor size and version fields that describe the passed structure.dwFlags and iPixelType: pixel-format capability flags and pixel type.cColorBits, cRedBits, cRedShift, cGreenBits, cGreenShift, cBlueBits, cBlueShift, cAlphaBits, and cAlphaShift: color-channel layout fields.cAccumBits, cAccumRedBits, cAccumGreenBits, cAccumBlueBits, and cAccumAlphaBits: accumulation-buffer layout fields.cDepthBits, cStencilBits, and cAuxBuffers: depth, stencil, and auxiliary-buffer counts.iLayerType, bReserved, dwLayerMask, dwVisibleMask, and dwDamageMask: layer and visibility mask fields."windows/gdi32" use

"dwDamageMask"ChoosePixelFormat selects one pixel-format ordinal for one device context from one PIXELFORMATDESCRIPTOR request and returns 0 when no format is selected.SetPixelFormat installs the selected ordinal into the same device context and returns one nonzero status on success.SwapBuffers presents one already configured double-buffered device context and returns one nonzero status on success.ChoosePixelFormat (hdc ppfd -- format): selects one pixel-format ordinal for one device context from one PIXELFORMATDESCRIPTOR request.SetPixelFormat (hdc format ppfd -- result): installs one selected pixel format into one device context.SwapBuffers (hdc -- result): swaps the front and back buffers of one double-buffered device context.Printing imported names during compilation shows the exact imported signatures.
