28 | | * @short_description: Interface for file descriptor based IO |
29 | | * @include: gio/gfiledescriptorbased.h |
30 | | * @see_also: #GInputStream, #GOutputStream |
31 | | * |
32 | | * #GFileDescriptorBased is implemented by streams (implementations of |
33 | | * #GInputStream or #GOutputStream) that are based on file descriptors. |
34 | | * |
35 | | * Note that `<gio/gfiledescriptorbased.h>` belongs to the UNIX-specific |
36 | | * GIO interfaces, thus you have to use the `gio-unix-2.0.pc` pkg-config |
37 | | * file when using it. |
