\f0\fs22 \cf0 HID Utilities Source\ Human Interface Device Manager Utility Functions\ \ Version 3.7 28 Oct 2K2\ General cleanup for web posting.\ \ Version 3.6 23 Oct 2K2\ Added new API's: HIDSetElementValue, HIDSetQueueCallback, HIDGetReport, HIDSetReport & HIDPrintElement,\ Note: <IOHIDPowerUsage.h> & <PID.h> have been incorporated into <IOKit/hid/IOHIDUsageTables.h>.\ \ Version 3.5 10 Aug 2K2\ HIDConfigureAction now only checks kHIDElementTypeInput elements.\ Changed some "for (x=0;x<n;x++) i[x] = 0;" code to use bzero instead.\ Moved device & element finding code into its own routines: HIDFindActionDeviceAndElement & HIDFindSubElement.\ The original HID utilities depended on the BSD FILE* implementation for HID[Save/Restore]ElementConfig and didn't work in CFM applications.\ So two new routine (HIDSaveElementPref & HIDRestoreElementPref) were added that use the CFPreferences API's instead. \ \ Version 3.4 Added code to support hot plugging & un-plugging devices. Note to developers: It's very important to use the HIDIsValidDevice\ and HIDIsValidElement API's to verify that cached device or element pointers are still valid before de-referencing them.\ This validation code has been added to all HID Utilities AIP's that take a device or element pointer as a parameter.\ Note also that this required that queueRunLoopSource and notification port fields be added to the device record. (see <HID_Utilities.h>)\ \ Version 3.3 Added output transaction support for UPS & FFB devices (see <HID_Transaction_Utilities.c> & <HID_Transaction_Utilities.h>).\ \ Version 3.2 Since 10.2 changed the cookie numbers (by adding a usage == -1element for arrays) a cookie agnostic method of getting\ device and element names was needed. Plus the nested (device & element) switch statements hardcoding the strings.\ So all the device, element & cookie strings have been moved out of the source file(s) and put into XML data files instead.\ NOTE: all local (static) routines now begin with "hid_" instead of "HID".\ All references to "Kernel/IOKit/hidsystem/" now (correctly) point to "IOKit/hid/" instead.\ \ Version 3.1: Added the basics of a element naming scheme. Right now it just supports one device (macally iShock) but as I get more \ device info I can add other devices (feel free to add to the name lookup file and send me the results). Added bad device \ and element chencking in config/save. Fixed one case of swapped usage page and usage variables. Fixed a few leaks \ noted by a developer. Add a NULL check to top level element handler to prevent NULL deference also noted by developer. \ Checked build with gcc3. Rebuilt bundle and static lib.\ \ Version 3.0: Major Change: Added CFM support.\ Project now can be built in three different ways with the interface being straight C with Mac OS X type reliance, thus completely\ suitable for CFM or MachO binary formats and Carbon, Cocoa, or command line interfaces.\ \ - Static Library: For use with Mac OS X MachO projects. The build product (in the build directory) can be static linked\ into any exisiting Mac OS X MachO project. The project should include HID_Utilities_External.h only for declarations.\ \ - Source: This is just including the HID Utilities source files in the target project. Works as previous, but now all the \ declarations needed are in the HID_Utilities_External.h header file.\ \ - Dynamic Library: Should only be used by CFM applications. There are some notes which MUST be followed. See the HID Explorer\ or the HID Config Save samples for CW7 projects which show the actual use of the library. The dylib is housed in a bundle\ which the CFM app finds at runtime and calls into. This bundle is included and the dylib project will automatically place\ the actual dylib in the bundle (contents/MacOS/). NOTE: The path to this is an absolute path for the build product of the \ project, you MUST modify this if you rebuild the dylib (which never be required). To do this select the prject name in the\ Files tab and Get Info. Point the build product to the HID.bundle/contents/MacOS/ directory in the HID Utilities directory.\ Then point the intermediates to the intermediates directory already in the build directory. This is required since the build\ product path is absolute and can't be project relative (yes, a bug has been filed). Again, this is only if you wnat to rebuild\ the dylib used for CFM applications. Also note, you must copy the HID.bundle into your application directory (if you are using\ the method in the sample to find the bundle) for your CFM application to use it.\ \ Other Notes:\ The interface is now completely Mac OS X type free. This means minor mods to your projects. See the element and device structures\ for guidence on the types. For example cookies now should be void *'s. Fixed a couple bugs in allocating queues. CLean up error\ checking to only dump DebugStrs if the source is used (vice the static or dynamic libraries).\ \ Version 2.0: Update. Fixed some 10.1 issues, notably spelling errors in constants and include differences. Fixed 10.0.x errors, notably \ type errors in retrieving element info, negative value handling (see GetElementValue), queuing error, and other minor changes.\ Major change in element list handling... Elements are now stored in a binary tree to mimic the tree sturcture of the \ device. This allows hierarchial diplay and parsing (See HID Explorer sample). Additionally, some of the routine declarations \ have chnaged to work with this tree structure, one can still get same list functionality by using GetNextDeviceElement routine \ with kHIDElementTypeIO constant. Collections are now stored in tree, so users of these functions must understand if they are \ looking at a valid IO element or a collection. Lastly, new parsing strings and two new headers are included to aid in decoding \ PID and power device elements.\ \ Version 1.0: Initial release featuring functions to get HID device list, get devices and elements, poll for values, setup queues and get events, \ handle configuration set up and saving/restoring of configurations.\ \ ----\ \ This group of utilities is stand alone code to help developers work more easily with the HID Manager for Mac OS X with both MachO and CFM support. \ It provides a high level abstract of the current HID interface that sacrifices slight flexibility in favor single function set up, device and element \ retrieval, current value and event query, and configuration. This sample is the source code for the Utilities and does not provide a sample of the \ utilization. There are other samples which provide complete working examples of a HID device explorer and a simple game implementation. More samples \ will be forth coming shortly.\ \ This set of utilities is constantly evolving to both address any bugs and provide better support for developer requested features.\ Any suggestions and/or bugs can be directed to the Apple bug reporter at:\ http://developer.apple.com/bugreporter/index.html\ \ // ==================================\ \ // Device and Element Interfaces\ \ enum
