Struct

GLibMappedFile

Description [src]

struct GMappedFile {
  /* No available fields */
}

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

Constructors

g_mapped_file_new

Maps a file into memory. On UNIX, this is using the mmap() function.

Available since: 2.8

g_mapped_file_new_from_fd

Maps a file into memory. On UNIX, this is using the mmap() function.

Available since: 2.32

Instance methods

g_mapped_file_free

This call existed before GMappedFile had refcounting and is currently exactly the same as g_mapped_file_unref().

Available since: 2.8

Deprecated since: 2.22

g_mapped_file_get_bytes

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.

Available since: 2.34

g_mapped_file_get_contents

Returns the contents of a GMappedFile.

Available since: 2.8

g_mapped_file_get_length

Returns the length of the contents of a GMappedFile.

Available since: 2.8

g_mapped_file_ref

Increments the reference count of file by one. It is safe to call this function from any thread.

Available since: 2.22

g_mapped_file_unref

Decrements the reference count of file by one. If the reference count drops to 0, unmaps the buffer of file and frees it.
