Utility method for GPollableInputStream and GPollableOutputStream implementations. Creates a new GSource that expects a callback of type GPollableSourceFunc. The new source does not actually do anything on its own; use g_source_add_child_source() to add other sources to it to cause it to trigger. Since 2.28
Utility method for GPollableInputStream and GPollableOutputStream implementations. Creates a new GSource, as with g_pollable_source_new(), but also attaching child_source (with a dummy callback), and cancellable, if they are non-NULL. Since 2.34
Tries to read from stream, as with g_input_stream_read() (if blocking is TRUE) or g_pollable_input_stream_read_nonblocking() (if blocking is FALSE). This can be used to more easily share code between blocking and non-blocking implementations of a method. If blocking is FALSE, then stream must be a GPollableInputStream for which g_pollable_input_stream_can_poll() returns TRUE, or else the behavior is undefined. If blocking is TRUE, then stream does not need to be a GPollableInputStream. Since 2.34
Tries to write to stream, as with g_output_stream_write() (if blocking is TRUE) or g_pollable_output_stream_write_nonblocking() (if blocking is FALSE). This can be used to more easily share code between blocking and non-blocking implementations of a method. If blocking is FALSE, then stream must be a GPollableOutputStream for which g_pollable_output_stream_can_poll() returns TRUE or else the behavior is undefined. If blocking is TRUE, then stream does not need to be a GPollableOutputStream. Since 2.34
Tries to write count bytes to stream, as with g_output_stream_write_all(), but using g_pollable_stream_write() rather than g_output_stream_write(). On a successful write of count bytes, TRUE is returned, and bytes_written is set to count. If there is an error during the operation (including G_IO_ERROR_WOULD_BLOCK in the non-blocking case), FALSE is returned and error is set to indicate the error status, bytes_written is updated to contain the number of bytes written into the stream before the error occurred. As with g_pollable_stream_write(), if blocking is FALSE, then stream must be a GPollableOutputStream for which g_pollable_output_stream_can_poll() returns TRUE or else the behavior is undefined. If blocking is TRUE, then stream does not need to be a GPollableOutputStream. Since 2.34
