Helpers

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

like failIfFalse_, but retried on sharing violations. This is necessary for many file operations; see http://support.microsoft.com/kb/316609

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

File operations

HANDLE operations

Reading/writing

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

File notifications

Directories

DOS device flags

File locks

lockFile Source #

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.
