SP_DEVICE_INTERFACE_DETAIL_DATA_W structure (setupapi.h)

An SP_DEVICE_INTERFACE_DETAIL_DATA structure contains the path for a device interface.

Syntax

typedef struct _SP_DEVICE_INTERFACE_DETAIL_DATA_W {
  DWORD cbSize;
  WCHAR DevicePath[ANYSIZE_ARRAY];
} SP_DEVICE_INTERFACE_DETAIL_DATA_W, *PSP_DEVICE_INTERFACE_DETAIL_DATA_W;

Members

cbSize

The size, in bytes, of the SP_DEVICE_INTERFACE_DETAIL_DATA structure. For more information, see the following Remarks section.

DevicePath[ANYSIZE_ARRAY]

A NULL-terminated string that contains the device interface path. This path can be passed to Win32 functions such as CreateFile.

Remarks

An SP_DEVICE_INTERFACE_DETAIL_DATA structure identifies the path for a device interface in a device information set.

SetupDiXxx functions that take an SP_DEVICE_INTERFACE_DETAIL_DATA structure as a parameter verify that the cbSize member of the supplied structure is equal to the size, in bytes, of the structure. If the cbSize member is not set correctly for an input parameter, the function will fail and set an error code of ERROR_INVALID_PARAMETER. If the cbSize member is not set correctly for an output parameter, the function will fail and set an error code of ERROR_INVALID_USER_BUFFER.

Note

The setupapi.h header defines SP_DEVICE_INTERFACE_DETAIL_DATA as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
