* @short_description: Interface for file descriptor based IO
* @include: gio/gfiledescriptorbased.h
* @see_also: #GInputStream, #GOutputStream
*
* #GFileDescriptorBased is implemented by streams (implementations of
* #GInputStream or #GOutputStream) that are based on file descriptors.
*
* Note that <filename>&lt;gio/gfiledescriptorbased.h&gt;</filename> belongs to
* the UNIX-specific GIO interfaces, thus you have to use the
* <filename>gio-unix-2.0.pc</filename> pkg-config file when using it.
*
* Since: 2.24
