Members

Functions

addRef void addRef(FileFD descriptor): Increments the reference count of the given file.
adopt FileFD adopt(int system_file_handle): Undocumented in source.
cancelRead void cancelRead(FileFD file): Cancels an ongoing read operation.
cancelWrite void cancelWrite(FileFD file): Cancels an ongoing write operation.
close void close(FileFD file, FileCloseCallback on_closed): Disallows any reads/writes and removes any exclusive locks.
getSize ulong getSize(FileFD file): Undocumented in source.
isValid bool isValid(FileFD handle): Determines whether the given file handle is valid.
open FileFD open(string path, FileOpenMode mode): Undocumented in source.
rawUserData void* rawUserData(FileFD descriptor, size_t size, DataInitializer initialize, DataInitializer destroy): Low-level user data access. Use userData instead.
read void read(FileFD file, ulong offset, ubyte[] buffer, IOMode mode, FileIOCallback on_read_finish): Reads data from a file.
releaseRef bool releaseRef(FileFD descriptor): Decrements the reference count of the given file.
truncate void truncate(FileFD file, ulong size, FileIOCallback on_finish): Shrinks or extends a file to the specified size.
write void write(FileFD file, ulong offset, const(ubyte)[] buffer, IOMode mode, FileIOCallback on_write_finish): Writes data to a file

Properties

userData FileFD userData [@property setter]: Retrieves a reference to a user-defined value associated with a descriptor.
