Helpers

failIfWithRetry :: (a -> Bool) -> String -> IO a -> IO a Source #

like failIf, but retried on sharing violations. This is necessary for many file operations; see https://www.betaarchive.com/wiki/index.php/Microsoft_KB_Archive/316609

failIfWithRetry_ :: (a -> Bool) -> String -> IO a -> IO () Source #

failIfFalseWithRetry_ :: String -> IO Bool -> IO () Source #

File operations

deleteFile :: String -> IO () Source #

copyFile :: String -> String -> Bool -> IO () Source #

moveFile :: String -> String -> IO () Source #

moveFileEx :: String -> Maybe String -> MoveFileFlag -> IO () Source #

setCurrentDirectory :: String -> IO () Source #

createDirectory :: String -> Maybe LPSECURITY_ATTRIBUTES -> IO () Source #

createDirectoryEx :: String -> String -> Maybe LPSECURITY_ATTRIBUTES -> IO () Source #

removeDirectory :: String -> IO () Source #

getBinaryType :: String -> IO BinaryType Source #

getTempFileName Source #

Arguments

:: String	directory for the temporary file (must be at most MAX_PATH - 14 characters long)
-> String	prefix for the temporary file name
-> Maybe UINT	if `Nothing`, a unique name is generated otherwise a non-zero value is used as the unique part
-> IO (String, UINT)

Get a unique temporary filename.

Calls GetTempFileNameW.

HANDLE operations

createFile :: String -> AccessMode -> ShareMode -> Maybe LPSECURITY_ATTRIBUTES -> CreateMode -> FileAttributeOrFlag -> Maybe HANDLE -> IO HANDLE Source #

createFile_NoRetry :: String -> AccessMode -> ShareMode -> Maybe LPSECURITY_ATTRIBUTES -> CreateMode -> FileAttributeOrFlag -> Maybe HANDLE -> IO HANDLE Source #

Like createFile, but does not use failIfWithRetry. If another process has the same file open, this will fail.

closeHandle :: HANDLE -> IO () Source #

getFileType :: HANDLE -> IO FileType Source #

flushFileBuffers :: HANDLE -> IO () Source #

setEndOfFile :: HANDLE -> IO () Source #

setFileAttributes :: String -> FileAttributeOrFlag -> IO () Source #

getFileAttributes :: String -> IO FileAttributeOrFlag Source #

getFileAttributesExStandard :: String -> IO WIN32_FILE_ATTRIBUTE_DATA Source #

getFileInformationByHandle :: HANDLE -> IO BY_HANDLE_FILE_INFORMATION Source #

Reading/writing

Some operations below bear the win32_ prefix to avoid shadowing operations from Prelude.

Arguments

:: HANDLE	CreateFile handle
-> LockMode	Locking mode
-> DWORD64	Size of region to lock
-> DWORD64	Beginning offset of file to lock
-> IO BOOL	Indicates if locking was successful, if not query getLastError.

Locks a given range in a file handle, To lock an entire file use 0xFFFFFFFFFFFFFFFF for size and 0 for offset.

unlockFile Source #

Arguments

:: HANDLE	CreateFile handle
-> DWORD64	Size of region to unlock
-> DWORD64	Beginning offset of file to unlock
-> IO BOOL	Indicates if unlocking was successful, if not query getLastError.

Unlocks a given range in a file handle, To unlock an entire file use 0xFFFFFFFFFFFFFFFF for size and 0 for offset.
