29 | | * GFileDescriptorBased: |
30 | | * |
31 | | * `GFileDescriptorBased` is an interface for file descriptor based IO. |
32 | | * |
33 | | * It is implemented by streams (implementations of [class@Gio.InputStream] or |
34 | | * [class@Gio.OutputStream]) that are based on file descriptors. |
35 | | * |
36 | | * Note that `<gio/gfiledescriptorbased.h>` belongs to the UNIX-specific |
37 | | * GIO interfaces, thus you have to use the `gio-unix-2.0.pc` pkg-config |
38 | | * file or the `GioUnix-2.0` GIR namespace when using it. |
39 | | * |
40 | | * Since: 2.24 |
