HidP_SetButtons (Windows Embedded CE 6.0)

1/6/2010

This macro is a mnemonic alias for the HidP_SetUsages function.

Syntax

#define HidP_SetButtons(Rty, Up, Lco, ULi, ULe, Ppd, Rep, Rle) \
        HidP_SetUsages(Rty, Up, Lco, ULi, ULe, Ppd, Rep, Rle)

Rty
[in] HIDP_REPORT_TYPE enumerator value that indicates the type of report located at Rep.

Lco
[in] Link collection that contains the usages. If LinkCollection is nonzero, the function only sets the usages, if they exist, in this link collection. If LinkCollection is zero, the function sets the first usage for each specified usage in the top-level collection associated with PreparsedData.

ULe
[in, out] On input, the number of usages in UsageList. On output, if HidP_SetUsages cannot set a usage in UsageList, the function sets UsageLength to the index of the usage that cannot be set, and returns a status value that indicates the error.

Ppd
[in] Pointer to the preparsed data of the top-level collection associated with the report located at Report.

Rep
[in, out] On input, an initialized report. On output, a pointer to a report.

Rle
[in] Size, in bytes, of the report located at Rep, which must be equal to the report length for the specified report type that HidP_GetCaps returns in a collection's HIDP_CAPS structure.

The following table shows the possible return values.

Value	Description
HIDP_STATUS_SUCCESS	The function has successfully set the usage value.
HIDP_STATUS_BUFFER_TOO_SMALL	A usage in a button array cannot be set because the array is already fully set.
HIDP_STATUS_INVALID_REPORT_LENGTH	Report length is not valid.
HIDP_STATUS_INVALID_REPORT_TYPE	Specified report type is not valid.
HIDP_STATUS_INCOMPATIBLE_REPORT_ID	Report contains a collection with buttons in the specified usage page, but there are no such usages in the report.
HIDP_STATUS_INVALID_PREPARSED_DATA	Preparsed data is not valid.
HIDP_STATUS_USAGE_NOT_FOUND	Report contains a requested usage that is not in any report supported by the top-level collection.

The terms button and usage are used synonymously.
