SetupGetInfFileList
[New
- Windows NT]
The SetupGetInfFileList
function returns a list of INF files located in a caller-specified directory to
a call-supplied buffer.
BOOL SetupGetInfFileList(
|
PCTSTR DirectoryPath, |
// optional, the
directory path |
|
DWORD InfStyle, |
// style of the
INF file |
|
PTSTR ReturnBuffer, |
// optional,
receives the file list |
|
DWORD ReturnBufferSize, |
// size of the
supplied buffer |
|
PDWORD RequiredSize |
// optional,
buffer size needed |
|
); |

Parameters
DirectoryPath
An optional
parameter that points to a null-terminated string containing the path of the
directory in which to search. If this value is NULL, the %windir%\inf
directory is used.
InfStyle
Specifies the
style of INF file to search for. May be a combination of the following flags.
INF_STYLE_OLDNT
Windows NT
3.x script-based INF files.
INF_STYLE_WIN4
Windows 95-
or Windows NT 4.0-style INF files.
ReturnBuffer
If not NULL,
points to a caller-supplied buffer in which this function returns the list of
all INF files of the desired style(s) that were found in the specified
subdirectory. Filenames are null-terminated, with an extra null at the end of
the list. The filenames do not include the path.
ReturnBufferSize
Specifies the
size of the buffer pointed to by the ReturnBuffer parameter. If ReturnBuffer
is not specified, ReturnBufferSize is ignored.
RequiredSize
If not NULL,
points to a caller-supplied variable in which this function returns the
required size for the buffer pointed to by the ReturnBuffer parameter.
If ReturnBuffer is specified and the size needed is larger than ReturnBufferSize,
the function fails and a call to GetLastError11C2VS7 returns ERROR_INSUFFICIENT_BUFFER.
Return Values
If the
function succeeds, the return value is TRUE.
If the
function fails, the return value is FALSE. To get extended error information,
call GetLastError.
Remarks
For the
Unicode version of this function, the buffer sizes ReturnBufferSize, and
RequiredSize are specified in number of characters. This number includes
the null terminator. For the ANSI version of this function, the sizes are
specified in number of bytes.
If this
function is called with a ReturnBuffer of NULL and a ReturnBufferSize of
zero, the function puts the buffer size needed to hold the specified data into
the variable pointed to by RequiredSize. If the function succeeds in
this, the return value is TRUE. Otherwise, the return value is FALSE and
extended error information can be obtained by calling GetLastError.
Thus, you can
call the function once to get the required buffer size, allocate the necessary
memory, and then call the function a second time to retrieve the data. Using
this technique, you can avoid errors due to an insufficient buffer size.
If multiple
INF file styles are returned by this function, the style of a particular INF
file can be determined by calling the SetupGetInfInformation function.
