Vk/VkTrace(3) -- Utility routines for tracing ViewKit applications
|
|
This package is a set of functions that can be used to generate time-stamped traces from within ViewKit applications. Traces are normal ASCII files, intended for human perusal. For normal VkApp applications, the user must insert all calls into the source, including initialization from within the application. For VkMsgApp applications, initialization, and some calls are already present. GLOBAL VARIABLE CONTROLS Tracing is controlled by global variables that should be set as early as possible with... |

Vk/VkVisual(3) -- convenience class for dealing with X11 visuals
|
|
Dealing with the interaction between widgets and X11 visuals can get complicated. Some applications either get it wrong, or else stick with the default visual when another would be more appropriate. Code, even library code, that assumes default visual attributes is commonplace. Such an assumption is especially bad in a library, because libraries must work with applications that use non-default visuals. VkVisual() makes it easy for an application to set up the X11 visual information it needs. Usi... |

Vk/VkWarningDialog(3) -- Dialog manager class for warning dialogs

VkWebViewerBase(3) -- Web viewing component

|
Vk/VkWidgetList(3) -- Supports operations on a list of widgets
|
|
The VkWidgetList class provides a convenient way to maintain and manipulate lists of widgets. Widgets can be added and removed from the list, or accessed by index. The VkWidgetList adds a destroyCallback to each added widget to maintain the integrity of the list when widgets are destroyed. |

video/vlbufferreset(3d) -- VL buffer state management routines
|
|
svr Specifies the server handle. path Specifies the path handle. node Specifies the node handle. buffer Specifies the buffer handle. advice Specifies the advice for the buffer. |
|
video/vlcallbacks(3d) -- IRIS VL event handling routines
|
|
svr Specifies the video server. fd a file descriptor that can be used with select(2). handler Pointer to a function to handle data valid on the file descriptor. pendingFunc Pointer to a function that will tell whether there is data that has been read from the file descriptor, but not passed to a handler function. If this is null, no data will be checked for before entering select(2). clientData Data for the use of the client callback. path The path for which a callback will be invoked, of VL_ANY... |

video/vlcreatebuffer(3d) -- IRIS VL buffer create and destroy routines
|
|
vlCreateBuffer creates and returns a handle to a buffer which can then be registered with a path and used to send or receive video data. A VLBuffer consists of a list of frame-sized regions of memory each with an associated header block. Buffers are needed for transferring data to or from memory nodes. To receive a frame, the reader calls one of vlGetNextValid or vlGetLatestValid , and to free that frame calls vlPutFree. To send a frame, the writer calls vlGetNextFree, copies the data to be sent... |

video/vlcreatepath(3d) -- manage VL paths
|
|
svr Specifies the server handle. vlDev Specifies the device handle. path Specifies the path handle. source Specifies the source node. drain Specifies the drain node. |
|
video/vlDMBufferGetValid(3d) -- VL DMbuffer management routines
|
|
vlDMBufferGetValid returns a valid DMbuffer containing video data from the specified node and path. This call is used in video capture-type applications where a path is set up to route image data from a source video device node to drain memory node. The buffer that is returned contains one video image, either a field or a frame. dmBufferMapData can be used to get a pointer to the image in the buffer. The contents of the buffer should not be modified. vlDMBufferPutValid takes a valid DMbuffer and... |
|
video/vldmbuffersend(3d) -- send a DMbuffer to video out.
|
|
vlDMBufferSend puts the DMbuffer on the specified paths output drain queue. Care must be taken not to overflow this queue by adding buffers faster than the video library can dequeue them and send them out. This call should be synchronized with VLTransferComplete events from the path which indicates a buffer has been sent out. |
|
video/vlDMGetParams(3d) -- get DMparams list for video subsystem
|
|
vlDMGetParams queries the video subsystem for a list of parameters describing the characteristics of a specified node and path. This parameter list is required to create a DMbufferpool which can be used for video transfers on the same path and memory node. vlDMGetParams should be called after dmBufferSetPoolDefaults(3dm) and before dmBufferCreatePool(3dm). |
