Functions
| HidP_GetButtonArray HidP_GetButtonArray returns an array of HIDP_BUTTON_ARRAY_DATA structures for the specified report. |

| HidP_GetLinkCollectionNodes The HidP_GetLinkCollectionNodes routine returns a top-level collection's link collection array. |
| HidP_GetScaledUsageValue The HidP_GetScaledUsageValue routine returns the signed and scaled result of a HID control value extracted from a HID report. |
| HidP_GetSpecificButtonCaps The HidP_GetSpecificButtonCaps routine returns a button capability array that describes all HID control buttons in a top-level collection that meet a specified selection criteria. |
| HidP_GetSpecificValueCaps The HidP_GetSpecificValueCaps routine returns a value capability array that describes all HID control values that meet a specified selection criteria. |
| HidP_GetUsages The HidP_GetUsages routine returns a list of all the HID control button usages that are on a specified usage page and are set to ON in a HID report. |
| HidP_GetUsagesEx The HidP_GetUsagesEx routine returns a list of the all the HID control button usages that are set to ON in a HID report. |
| HidP_GetUsageValue The HidP_GetUsageValue routine extracts the data associated with a HID control value that matches the selection criteria in a HID report. |
| HidP_GetUsageValueArray The HidP_GetUsageValueArray routine extracts the data associated with a HID control usage value array from a HID report. |
| HidP_GetValueCaps The HidP_GetValueCaps routine returns a value capability array that describes all the HID control values in a top-level collection for a specified type of HID report. |
| HidP_GetVersion The HidP_GetVersion function is a header-only implementation that returns the HID API version. |
| HidP_InitializeReportForID The HidP_InitializeReportForID routine initializes a HID report. |
| HidP_MaxDataListLength The HidP_MaxDataListLength routine returns the maximum number of HIDP_DATA structures that HidP_GetData can return for a specified type of HID report and a specified top-level collection. |
| HidP_MaxUsageListLength The HidP_MaxUsageListLength routine returns the maximum number of HID usages that HidP_GetUsages can return for a specified type of HID report and a specified top-level collection. |
| HidP_SetButtonArray The HidP_SetButtonArray function sets the state of buttons via an array of HIDP_BUTTON_ARRAY_DATA structures. |
| HidP_SetButtons The HidP_SetButtons macro is a mnemonic alias for the HidP_SetUsages function. |
| HidP_SetData The HidP_SetData routine sets a specified set of HID control button and value usages in a HID report. |
| HidP_SetScaledUsageValue The HidP_SetScaledUsageValue routine converts a signed and scaled physical number to a HID usage's logical value, and sets the usage value in a specified HID report. |
| HidP_SetUsages The HidP_SetUsages routine sets specified HID control buttons ON (1) in a HID report. |
| HidP_SetUsageValue The HidP_SetUsageValue routine sets a HID control value in a specified HID report. |
| HidP_SetUsageValueArray The HidP_SetUsageValueArray routine sets a HID control usage value array in a specified HID report. |
| HidP_TranslateUsagesToI8042ScanCodes The HidP_TranslateUsagesToI8042ScanCodes routine maps a list of HID usages on the HID_USAGE_PAGE_KEYBOARD usage page to their respective PS/2 scan codes (Scan Code Set 1). |
| HidP_UnsetButtons The HidP_UnsetButtons macro is a mnemonic alias for the HidP_UnsetUsages function. |
| HidP_UnsetUsages The HidP_UnsetUsages routine sets specified HID control button usages OFF (zero) in a HID report. |
| HidP_UsageAndPageListDifference The HidP_UsageAndPageListDifference function returns the difference between two lists of usages. |
| HidP_UsageListDifference The HidP_UsageListDifference routine returns the differences between two arrays of HID usages. |
Structures
| HIDP_BUTTON_ARRAY_DATA The HIDP_BUTTON_ARRAY_DATA structure is used to get or set data for single button in a button array. |
| HIDP_BUTTON_CAPS The HIDP_BUTTON_CAPS structure contains information about the capability of a HID control button usage (or a set of buttons associated with a usage range). |
| HIDP_CAPS The HIDP_CAPS structure contains information about a top-level collection's capability. |
| HIDP_DATA The HIDP_DATA structure contains information about a HID control's data index and value in a HID report. |
| HIDP_EXTENDED_ATTRIBUTES The HIDP_EXTENDED_ATTRIBUTES structure contains information about the global items specified for a HID control that the HID parser did not recognize. |
| HIDP_LINK_COLLECTION_NODE The HIDP_LINK_COLLECTION_NODE structure contains information about a link collection in a top-level collection's link collection array. |
| HIDP_UNKNOWN_TOKEN The HIDP_UNKNOWN_TOKEN structure contains information about a global item that the HID parser did not recognize. |
| HIDP_VALUE_CAPS The HIDP_VALUE_CAPS structure contains information that describes the capability of a set of HID control values (either a single usage or a usage range). |
| USAGE_AND_PAGE The USAGE_AND_PAGE structure specifies the usage page and usage ID of a HID control. |
Enumerations
| HIDP_REPORT_TYPE The HIDP_REPORT_TYPE enumeration type is used to specify a HID report type. |
