MappedFile

The #GMappedFile represents a file mapping created with g_mapped_file_new(). It has only private members and should not be accessed directly.

class MappedFile {

GMappedFile* gMappedFile;

bool ownedRef;

GMappedFile* getMappedFileStruct(bool transferOwnership);

void* getStruct();

this(GMappedFile* gMappedFile, bool ownedRef);

this(string filename, bool writable);

this(int fd, bool writable);

Bytes getBytes();

string getContents();

size_t getLength();

MappedFile doref();

void unref();

}

Constructors

this this(GMappedFile* gMappedFile, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(string filename, bool writable): Maps a file into memory. On UNIX, this is using the mmap() function.
this this(int fd, bool writable): Maps a file into memory. On UNIX, this is using the mmap() function.

Destructor

~this ~this(): Undocumented in source.

Members

Functions

doref MappedFile doref(): Increments the reference count of @file by one. It is safe to call this function from any thread.
free void free(): This call existed before #GMappedFile had refcounting and is currently exactly the same as g_mapped_file_unref().
getBytes Bytes getBytes(): Creates a new #GBytes which references the data mapped from @file. The mapped contents of the file must not be modified after creating this bytes object, because a #GBytes should be immutable.
getContents string getContents(): Returns the contents of a #GMappedFile.
getLength size_t getLength(): Returns the length of the contents of a #GMappedFile.
getMappedFileStruct GMappedFile* getMappedFileStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
unref void unref(): Decrements the reference count of @file by one. If the reference count drops to 0, unmaps the buffer of @file and frees it.

Variables

gMappedFile GMappedFile* gMappedFile;: the main Gtk struct
ownedRef bool ownedRef;: Undocumented in source.
