CeGetFileAttributes (RAPI)

  • Article

This function returns attributes for a specified file or directory. CeGetFileAttributes is a remote application interface (RAPI), which enables an application running on a desktop computer to make function calls on a Windows CE–based device.

DWORD CeGetFileAttributes(
LPCWSTR lpFileName);

Parameters

  • lpFileName
    [in] Long pointer to a null-terminated string that specifies the name of a file or directory.

    There is a default string size limit for paths of MAX_PATH characters. This limit is related to how the CeGetFileAttributes function parses paths. An application can transcend this limit and send in paths longer than MAX_PATH characters by prepending "\\?\" to the path. The "\\?\" tells the function to turn off path parsing; it lets paths longer than MAX_PATH be used with CeGetFileAttributes. However, each component in the path cannot be more than MAX_PATH characters long. This also works with Universal Naming Convention (UNC) names. The "\\?\" is ignored as part of the path. For example, "\\?\C:\myworld\private" is seen as "C:\myworld\private" and "\\?\UNC\bill_g_1\hotstuff\coolapps" is seen as "\\bill_g_1\hotstuff\coolapps."

Return Values

The attributes of the specified file or directory, returned in a DWORD, indicates success. 0xFFFFFFFF indicates failure. To determine if a function failed because of RAPI errors, call CeRapiGetError. To determine if a function failed because of non-RAPI errors, call CeGetLastError.

The attributes returned upon success can be one or more of the following values:

FILE_ATTRIBUTE_ARCHIVE

The file or directory is an archive file or directory. Applications use this attribute to mark files for backup or removal.

FILE_ATTRIBUTE_COMPRESSED

The file or directory is compressed. For a file, this means that all of the data in the file is compressed. For a directory, this means that compression is the default for newly created files and subdirectories.

FILE_ATTRIBUTE_DIRECTORY

The handle identifies a directory.

FILE_ATTRIBUTE_ENCRYPTED

The file or directory is encrypted. For a file, this means that all data streams are encrypted. For a directory, this means that encryption is the default for newly created files and subdirectories.

FILE_ATTRIBUTE_HIDDEN

The file or directory is hidden. It is not included in an ordinary directory listing.

FILE_ATTRIBUTE_INROM

This file is an operating system file stored in ROM. These files are read-only; they cannot be modified.

FILE_ATTRIBUTE_NORMAL

The file or directory has no other attributes set. This attribute is valid only if used alone.

FILE_ATTRIBUTE_READONLY

The file or directory is read-only. Applications can read the file but cannot write to it or delete it. In the case of a directory, applications cannot delete it.

FILE_ATTRIBUTE_REPARSE_POINT

The file has an associated reparse point.

FILE_ATTRIBUTE_ROMMODULE

This file is an operating system file stored in ROM and executed directly from ROM, rather than being first copied to RAM. The CreateFile function cannot be used to access this file, instead the LoadLibrary and CreateProcess functions must be used.

FILE_ATTRIBUTE_SPARSE_FILE

The file is a sparse file.

  • FILE_ATTRIBUTE_SYSTEM
    The file or directory is part of, or is used exclusively by, the operating system.
  • FILE_ATTRIBUTE_TEMPORARY
    The file is being used for temporary storage. File systems attempt to keep all of the data in memory for quicker access rather than flushing the data back to mass storage. A temporary file should be deleted by the application as soon as it is no longer needed.

Remarks

When writing applications for Windows CE versions 1.0 and 1.01, use the PegGetFileAttributes function.

Requirements

Runs On Versions Defined in Include Link to
Windows CE OS 2.0 and later Rapi.h
