HidD_GetManufacturerString function

The HidD_GetManufacturerString routine returns a top-level collection's embedded string that identifies the manufacturer.

Syntax

BOOLEAN HidD_GetManufacturerString(
  HANDLE HidDeviceObject,
  PVOID  Buffer,
  ULONG  BufferLength
);

Parameters

HidDeviceObject

Specifies an open handle to a top-level collection.

Buffer

Pointer to a caller-allocated buffer that the routine uses to return the collection's manufacturer string. The routine returns a NULL-terminated wide character string in a human-readable format.

BufferLength

Specifies the length, in bytes, of a caller-allocated buffer provided at Buffer. If the buffer is not large enough to return the entire NULL-terminated embedded string, the routine returns nothing in the buffer.

Return Value

HidD_HidD_GetManufacturerString returns TRUE if it returns the entire NULL-terminated embedded string. Otherwise, the routine returns FALSE. Use GetLastError to get extended error information.

Remarks

Only user-mode applications can call HidD_GetManufacturerString. Kernel-mode drivers can use an IOCTL_HID_GET_MANUFACTURER_STRING request.

The maximum possible number of characters in an embedded string is device specific. For USB devices, the maximum string length is 126 wide characters (not including the terminating NULL character).

For more information, see HID Collections.
