@topic Windows CE Object Store |
    The Windows CE object store has 3 parts - a registry API, a file system API and a database API. 
    <nl>The standard Win32 API's supported by the registry are:
    <nl>RegCloseKey 
    <nl>RegCreateKeyEx
    <nl>RegDeleteKey
    <nl>RegDeleteValue
    <nl>RegEnumValue
    <nl>RegEnumKeyEx
    <nl>RegOpenKeyEx
    <nl>RegQueryInfoKey
    <nl>RegQueryValueEx
    <nl>RegSetValueEx

    The standard Win32 API's supported by the filesytem are:
    <nl>CreateDirectory
    <nl>RemoveDirectory
    <nl>MoveFile
    <nl>CopyFile
    <nl>DeleteFile
    <nl>GetFileAttributes
    <nl>FindFirstFile
    <nl>CreateFileW
    <nl>ReadFile
    <nl>WriteFile
    <nl>GetFileSize
    <nl>SetFilePointer
    <nl>GetFileInformationByHandle
    <nl>FlushFileBuffers
    <nl>GetFileTime
    <nl>SetFileTime
    <nl>SetEndOfFile
    <nl>FindClose
    <nl>FindNextFile

    In addition, the following additional filesystem call is available:
    <nl>CreateContainer

    The various functions and data structures are described in this
    document.
