G_io_add_watch Example


This is because adding polling for a file descriptor is implemented in GLib on Windows by starting a thread that sits blocked in a read() from the file descriptor most of This channel will be closed when the last reference to it is dropped, so there is no need to call g_io_channel_close() (though doing so will not cause problems, as long as Parameters channel a GIOChannel   str_return The line read from the GIOChannel, including the line terminator. Please try again later.

When the reference count falls to 0, the GIOChannel is freed. (Though it isn't closed automatically, unless it was created using g_io_channel_new_from_file().) Using g_io_add_watch() or g_io_add_watch_full() increments a Members G_SEEK_CUR the current position in the file.   G_SEEK_SET the start of the file.   G_SEEK_END the end of the file.   enum GIOStatus Stati returned by most of EINVAL.Returns : a GIOChannelError error number, e.g. On system architectures which implement channel I/O, typically all devices are connected by channels, and so all I/O requires the use of CCWs.

G_io_add_watch Example

Once a GIOChannel has been created, it can be used in a generic manner with the functions g_io_channel_read_chars(), g_io_channel_write_chars(), g_io_channel_seek_position(), and g_io_channel_shutdown(). If the data is large, you could also just execute a postgres query to replace nulls with empty string -- that was the bug. If that happens a warning is issued, and GLib assumes that it is the file descriptor you mean. The new functions g-io-channel-read-chars, g-io-channel-read-line, g-io-channel-read-line-string, g-io-channel-read-to-end, g-io-channel-write-chars, g-io-channel-seek-position, and g-io-channel-flush should not be mixed with the deprecated functions g-io-channel-read, g-io-channel-write, and g-io-channel-seek on the same channel. 4.2 Usage — Class:

Here the virtual memory is page-fixed for the life of the application, rather than fixing and freeing around each I/O operation. channela line-termThe line termination string.

Booting with channel I/O[edit] Even bootstrapping of the system, or Initial Program Load (IPL) in IBM nomenclature, is carried out by channels, although the process is partially simulated by the CPU G_io_add_watch Example This function creates a GIOChannel that can be used to poll for Windows messages for the window in question. G_io_add_watch Socket Example Use g_io_channel_write_chars() instead.

The internal encoding is always UTF-8. Parameters en an errno error number, e.g. Sign in Share More Report Need to report the video? The above example is correct for unblocked records (one record per block). Giochannel Example

Parameters channel a GIOChannel   str_return Location to store a pointer to a string holding the remaining data in the GIOChannel. G_io_channel_read_chars Example This feature is not available right now. On large mainframe computer systems, CPUs are only one of several powerful hardware components that work in parallel.

Check the hardware and Clear the latched Errors on the IO Module and wait for it to happen again.

Hosted by Red Hat. You can do these steps manually if you need greater control. [rename-to g_io_add_watch] Parameters channel a GIOChannel   priority the priority of the GIOChannel source   condition the condition to watch The channel will not be freed until the last reference is dropped using g-io-channel-unref.

The channel will not be freed until the last reference is dropped using g_io_channel_unref(). modeOne of "r", "w", "a", "r+", "w+", "a+". Chaining[edit] IBM CCWs are chained to form the channel program. For example, if condition is , the source will be dispatched when there's data available for reading.

This IPL concept is device independent. This is a side-effect of the implementation and unavoidable. Try JIRA - bug tracking software for your team. errorA location to return an error of type .

str-return will contain allocated memory if the return is ‘G_IO_STATUS_NORMAL’. See the documentation for g_io_channel_set_encoding() for details.   error A location to return an error of type GIOChannelError   Returns the status of the operation. g_io_channel_shutdown () GIOStatus g_io_channel_shutdown ( on UNIX systems use g-io-channel-unix-new. The type G_SEEK_CUR is only allowed in those cases where a call to g_io_channel_set_encoding() is allowed.

You can get more info here. GIOChannel instances are created with an initial reference count of 1. On UNIX systems this works for plain files, pipes, and sockets. This can be nonzero even if the return value is not G_IO_STATUS_NORMAL.
