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

Syntax

BOOLEAN HidD_GetManufacturerString(
  [in]  HANDLE HidDeviceObject,
  [out] PVOID  Buffer,
  [in]  ULONG  BufferLength
Parameters
[in] HidDeviceObject
Specifies an open handle to a top-level collection.
[out] 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.
[in] 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. The supplied buffer must be <= 4093 bytes (2^12 – 3).
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).
If the supplied buffer is not <= 4093 bytes (2^12 – 3) the call may fail (depending on the underlying protocol, HID/Bluetooth/SPI) with error code ERROR_GEN_FAILURE (0x0000001f).
