module Foreign.Marshal.Error

data IOErrorType Source

An abstract type that contains a value for each variant of `IOError`.

Instances

Eq IOErrorType |
Show IOErrorType |

mkIOError :: IOErrorType -> String -> Maybe Handle -> Maybe FilePath -> IOError Source

Construct an `IOError` of the given type where the second argument describes the error location and the third and fourth argument contain the file handle and file path of the file involved in the error if applicable.

alreadyExistsErrorType :: IOErrorType Source

I/O error where the operation failed because one of its arguments already exists.

doesNotExistErrorType :: IOErrorType Source

I/O error where the operation failed because one of its arguments does not exist.

alreadyInUseErrorType :: IOErrorType Source

I/O error where the operation failed because one of its arguments is a single-use resource, which is already being used.

fullErrorType :: IOErrorType Source

I/O error where the operation failed because the device is full.

eofErrorType :: IOErrorType Source

I/O error where the operation failed because the end of file has been reached.

illegalOperationErrorType :: IOErrorType Source

I/O error where the operation is not possible.

permissionErrorType :: IOErrorType Source

I/O error where the operation failed because the user does not have sufficient operating system privilege to perform that operation.

userErrorType :: IOErrorType Source

I/O error that is programmer-defined.

annotateIOError :: IOError -> String -> Maybe Handle -> Maybe FilePath -> IOError Source

Adds a location description and maybe a file path and file handle to an `IOError`. If any of the file handle or file path is not given the corresponding value in the `IOError` remains unaltered.
