Syntax

NTSTATUS HidP_SetData(
  [in]      HIDP_REPORT_TYPE     ReportType,
  [in, out] PHIDP_DATA           DataList,
  [in, out] PULONG               DataLength,
  [in]      PHIDP_PREPARSED_DATA PreparsedData,
  [in]      PCHAR                Report,
  [in]      ULONG                ReportLength
);

Parameters

[in] ReportType

Specifies a HIDP_REPORT_TYPE enumerator value that indicates the type of HID report located at Report.

[in, out] DataList

Pointer to a caller-allocated array of HIDP_DATA structures that specify which buttons and usage values to set.

[in, out] DataLength

Specifies, on input, the number of members in the DataList array. For information about the output value, see the Remarks section.

[in] PreparsedData

Pointer to a top-level's preparsed data.

[in] Report

Pointer to a HID report.

[in] ReportLength

Specifies the size, in bytes, of the HID report located at Report, which must be equal to the report length for the specified report type that HidP_GetCaps returns in a collection's HIDP_CAPS structure.

Return value

HidP_SetData returns HIDP_STATUS_SUCCESS if it successfully sets all the control data specified by DataList.

HidP_SetData returns one of the following status values if one of the input parameters is not valid:

Return code	Description
HIDP_STATUS_INVALID_PREPARSED_DATA	The preparsed data specified by PreparsedData is not valid.
HIDP_STATUS_INVALID_REPORT_LENGTH	The size, in bytes, of the HID report is not equal to the length specified in the collection's HIDP_CAPS structure for the specified report type.
HIDP_STATUS_INVALID_REPORT_TYPE	ReportType is not valid.
HIDP_STATUS_REPORT_DOES_NOT_EXIST	The collection does not contain a report of the specified type.

 

HidP_SetData returns one of the following error values if one of the specified button or usage values could not be set:

Return code	Description
HIDP_STATUS_BUFFER_TOO_SMALL	A button in an array was not set to ON (1) because all the array fields are already used to index other buttons.
HIDP_STATUS_BUTTON_NOT_PRESSED	A DataList member specifies to set a button OFF (zero), but the button is already set to OFF.
HIDP_STATUS_DATA_INDEX_NOT_FOUND	The data index of a DataList member is not valid.
HIDP_STATUS_INCOMPATIBLE_REPORT_ID	A button or usage value is contained in a report, but it is not in the specified report.
HIDP_STATUS_IS_VALUE_ARRAY	A data index specifies a usage value array.

Remarks

Except for usage value arrays, a user-mode application or kernel-mode driver can use HidP_SetData to set buttons and usage values in a report. To set a usage value array, an application or driver must use HidP_SetUsageValueArray.

HidP_SetData sets the output value of DataLength as follows:
