Description

GUnixOutputStream implements GOutputStream for writing to a unix file descriptor, including asynchronous operations. The file descriptor must be selectable, so it doesn't work with opened files.

Note that <gio/gunixoutputstream.h> belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file when using it.

Details

struct GUnixOutputStream

struct GUnixOutputStream;

Implements GOutputStream for outputting to selectable unix file descriptors

g_unix_output_stream_new ()

GOutputStream *     g_unix_output_stream_new            (gint fd,
                                                         gboolean close_fd);

Creates a new GUnixOutputStream for the given fd.

If close_fd, is TRUE, the file descriptor will be closed when the output stream is destroyed.

fd :

 a UNIX file descriptor

close_fd :

 TRUE to close the file descriptor when done

Returns :

 a new GOutputStream

g_unix_output_stream_set_close_fd ()

void                g_unix_output_stream_set_close_fd   (GUnixOutputStream *stream,
                                                         gboolean close_fd);

Sets whether the file descriptor of stream shall be closed when the stream is closed.

stream :

 a GUnixOutputStream

close_fd :

 TRUE to close the file descriptor when done

Since 2.20

g_unix_output_stream_get_close_fd ()

gboolean            g_unix_output_stream_get_close_fd   (GUnixOutputStream *stream);

Returns whether the file descriptor of stream will be closed when the stream is closed.

stream :

 a GUnixOutputStream

Returns :

 TRUE if the file descriptor is closed when done

Since 2.20

g_unix_output_stream_get_fd ()

gint                g_unix_output_stream_get_fd         (GUnixOutputStream *stream);

Return the UNIX file descriptor that the stream writes to.

stream :

 a GUnixOutputStream

Returns :

 The file descriptor of stream

Since 2.20

Property Details

The "close-fd" property

  "close-fd"                 gboolean              : Read / Write

Whether to close the file descriptor when the stream is closed.

Default value: TRUE

Since 2.20

The "fd" property

  "fd"                       gint                  : Read / Write / Construct Only

The file descriptor that the stream writes to.

Default value: -1

Since 2.20
