type FileFlag = CInt

pattern O_APPEND :: FileFlag

The file is opened in append mode. Before each write, the file offset is positioned at the end of the file.

pattern O_CREAT :: FileFlag

The file is created if it does not already exist.

pattern O_DIRECT :: FileFlag

File IO is done directly to and from user-space buffers, which must be aligned. Buffer size and address should be a multiple of the physical sector size of the block device, (DO NOT USE WITH Z-IO's BufferedIO)

pattern O_DIRECTORY :: FileFlag

If the path is not a directory, fail the open. (Not useful on regular file)

Note O_DIRECTORY is not supported on Windows.

pattern O_DSYNC :: FileFlag

The file is opened for synchronous IO. Write operations will complete once all data and a minimum of metadata are flushed to disk.

Note O_DSYNC is supported on Windows via FILE_FLAG_WRITE_THROUGH.

pattern O_EXCL :: FileFlag

If the O_CREAT flag is set and the file already exists, fail the open.

Note In general, the behavior of O_EXCL is undefined if it is used without O_CREAT. There is one exception: on Linux 2.6 and later, O_EXCL can be used without O_CREAT if pathname refers to a block device. If the block device is in use by the system (e.g., mounted), the open will fail with the error EBUSY.

pattern O_EXLOCK :: FileFlag

Atomically obtain an exclusive lock.

Note UV_FS_O_EXLOCK is only supported on macOS and Windows. (libuv: Changed in version 1.17.0: support is added for Windows.)

pattern O_NOATIME :: FileFlag

Do not update the file access time when the file is read.

Note O_NOATIME is not supported on Windows.

pattern O_NOCTTY :: FileFlag

If the path identifies a terminal device, opening the path will not cause that terminal to become the controlling terminal for the process (if the process does not already have one). (Not sure if this flag is useful)

Note O_NOCTTY is not supported on Windows.

pattern O_NOFOLLOW :: FileFlag

If the path is a symbolic link, fail the open.

Note O_NOFOLLOW is not supported on Windows.

pattern O_NONBLOCK :: FileFlag

Open the file in nonblocking mode if possible. (Definitely not useful in Z-IO)

Note O_NONBLOCK is not supported on Windows. (Not useful on regular file anyway)

pattern O_RANDOM :: FileFlag

Access is intended to be random. The system can use this as a hint to optimize file caching.

Note O_RANDOM is only supported on Windows via FILE_FLAG_RANDOM_ACCESS.

pattern O_RDONLY :: FileFlag

Open the file for read-only access.

pattern O_RDWR :: FileFlag

Open the file for read-write access.

pattern O_SEQUENTIAL :: FileFlag

Access is intended to be sequential from beginning to end. The system can use this as a hint to optimize file caching.

Note O_SEQUENTIAL is only supported on Windows via FILE_FLAG_SEQUENTIAL_SCAN.

pattern O_SHORT_LIVED :: FileFlag

The file is temporary and should not be flushed to disk if possible.

Note O_SHORT_LIVED is only supported on Windows via FILE_ATTRIBUTE_TEMPORARY.

pattern O_SYMLINK :: FileFlag

Open the symbolic link itself rather than the resource it points to.

pattern O_SYNC :: FileFlag

The file is opened for synchronous IO. Write operations will complete once all data and all metadata are flushed to disk.

Note O_SYNC is supported on Windows via FILE_FLAG_WRITE_THROUGH.

pattern O_TEMPORARY :: FileFlag

The file is temporary and should not be flushed to disk if possible.

Note O_TEMPORARY is only supported on Windows via FILE_ATTRIBUTE_TEMPORARY.

pattern O_TRUNC :: FileFlag

If the file exists and is a regular file, and the file is opened successfully for write access, its length shall be truncated to zero.

pattern O_WRONLY :: FileFlag

Open the file for write-only access.

type Whence = CInt

pattern SEEK_SET :: Whence

Beginning of the file.

pattern SEEK_CUR :: Whence

Current position of the file pointer.

pattern SEEK_END :: Whence

End of file.

type CopyFileFlag = CInt

Flags control copying.

• COPYFILE_EXCL: If present, uv_fs_copyfile() will fail with UV_EEXIST if the destination path already exists. The default behavior is to overwrite the destination if it exists.
• COPYFILE_FICLONE: If present, uv_fs_copyfile() will attempt to create a copy-on-write reflink. If the underlying platform does not support copy-on-write, then a fallback copy mechanism is used.
• COPYFILE_FICLONE_FORCE: If present, uv_fs_copyfile() will attempt to create a copy-on-write reflink. If the underlying platform does not support copy-on-write, or an error occurs while attempting to use copy-on-write, then an error is returned.

type ProcessFlag = CUInt

pattern PROCESS_SETUID :: ProcessFlag

Set the child process' user id.

This is not supported on Windows, uv_spawn() will fail and set the error to UV_ENOTSUP.

pattern PROCESS_SETGID :: ProcessFlag

Set the child process' user id.

This is not supported on Windows, uv_spawn() will fail and set the error to UV_ENOTSUP.

pattern PROCESS_WINDOWS_VERBATIM_ARGUMENTS :: ProcessFlag

Do not wrap any arguments in quotes, or perform any other escaping, when converting the argument list into a command line string.

This option is only meaningful on Windows systems. On Unix it is silently ignored.

pattern PROCESS_DETACHED :: ProcessFlag

Spawn the child process in a detached state

This will make it a process group leader, and will effectively enable the child to keep running after the parent exits.

pattern PROCESS_WINDOWS_HIDE :: ProcessFlag

Hide the subprocess window that would normally be created.

This option is only meaningful on Windows systems. On Unix it is silently ignored.

pattern PROCESS_WINDOWS_HIDE_CONSOLE :: ProcessFlag

Hide the subprocess console window that would normally be created.

This option is only meaningful on Windows systems. On Unix it is silently ignored.

pattern PROCESS_WINDOWS_HIDE_GUI :: ProcessFlag

Hide the subprocess GUI window that would normally be created.

This option is only meaningful on Windows systems. On Unix it is silently ignored.

data ProcessOptions

ProcessOptions

Fields

• processFile :: CBytes

  Path pointing to the program to be executed.

• processArgs :: [CBytes]

  Command line arguments. On Windows this uses CreateProcess which concatenates the arguments into a string this can cause some strange errors. See the PROCESS_WINDOWS_VERBATIM_ARGUMENTS.

• processEnv :: Maybe [(CBytes, CBytes)]

  Optional environment(otherwise inherit from the current process).

• processCWD :: CBytes

  Current working directory for the subprocess.

• processFlags :: ProcessFlag

  Various flags that control how spawn behaves

• processUID :: UID

  This happens only when the appropriate bits are set in the flags fields.

• processGID :: GID

  This happens only when the appropriate bits are set in the flags fields.

• processStdStreams :: (ProcessStdStream, ProcessStdStream, ProcessStdStream)

  Specifying how (stdin, stdout, stderr) should be passed/created to the child, see ProcessStdStream
