I O Channel Error

Contents

Once the operating system has prepared a complete list of channel commands, it executes a single I/O machine instruction to initiate the channel program; the channel thereafter assumes control of the I/O operations until they are completed.

UW eScience Institute member stechu commented May 23, 2014 All the data is generated by other queries.

The channel is a file, and the file pointer was just repositioned by a call to g_io_channel_seek_position(). (This flushes all the internal buffers.) The current encoding is NULL or UTF-8. Auto detection breaks on "\n", "\r\n", "\r", "\0", and the Unicode paragraph separator. Since most real-world applications of mainframe systems are heavily I/O-intensive business applications, this architecture helps provide the very high levels of throughput that distinguish mainframes from other types of computer.

G_io_add_watch Example

For example, on IBM's Linux/390, the formatting of an entire track of a DASD requires only one channel program (and thus only one I/O instruction), but multiple channel command words (one per block). For example, if condition is G_IO_IN, the source will be dispatched when there's data available for reading. If that happens a warning is issued, and GLib assumes that it is the file descriptor you mean. Published on May 23, 2016How to deal with error IO channel count for current playback device has changed.

The channel buffers have been flushed and possibly io_close has been called by the time this function is called.   io_set_flags () sets the GIOFlags on the channel. IBM Systems Journal. 15 (1): 102–116. Parameters channel a GIOChannel   encoding the encoding type. [allow-none] error location to store an error of type GConvertError   Returns G_IO_STATUS_NORMAL if the encoding was successfully set g_io_channel_get_close_on_unref () gboolean g_io_channel_get_close_on_unref (GIOChannel *channel); Returns whether the file/socket/whatever associated with channel will be closed when channel receives its final unref and is destroyed. G_io_channel_shutdown Example Use g_io_channel_shutdown() instead.

If buffer already contains data, the old data will be overwritten.terminator_pos: location to store position of line terminator, or NULLerror: a location to store an error of type GConvertError or GIOChannelErrorReturns : the status of the operation.

g_io_channel_read_to_end ()GIOStatus g_io_channel_read_to_end (GIOChannel *channel, gchar **str_return, gsize *length, GError **error);Reads all the remaining data from the file.

Return value: G_IO_STATUS_NORMAL on success. G_io_channel_unix_new Rating is available when the video has been rented. Parameters fd a file descriptor.   Returns a new GIOChannel. g_io_channel_unix_get_fd () gint g_io_channel_unix_get_fd (GIOChannel *channel); Returns the file descriptor of the GIOChannel. Functions g_io_channel_unix_new () GIOChannel * g_io_channel_unix_new (int fd); Creates a new GIOChannel given a file descriptor.

This is called from g_io_channel_seek() on channels that support it.   io_close () closes the channel. Giocondition The channel will not be freed until the last reference is dropped using g_io_channel_unref().

G_io_channel_unix_new

Its transistorized successor, the IBM 7090,[2] had two or more channels (the 7607) and a channel multiplexor (the 7606) which could control up to eight channels.

Parameters channel a GIOChannel   g_io_create_watch () GSource * g_io_create_watch (GIOChannel *channel, GIOCondition condition); Creates a GSource that's dispatched when condition is met for the given channel .

G_io_add_watch Socket Example A value of ‘#f’ indicates auto detection.

Use NULL for auto detect. New code should use g_io_channel_read_chars() instead.

channel: a GIOChannel. buf: a buffer to read the data into (which should be at least count bytes long).count: the number of bytes to read from the GIOChannel.bytes_read: returns the number of bytes actually read. Returns : G_IO_ERROR_NONE if the operation was successful.

enum GIOErrortypedef enum { G_IO_ERROR_NONE, G_IO_ERROR_AGAIN, G_IO_ERROR_INVAL, G_IO_ERROR_UNKNOWN } GIOError;GIOError is only used by the deprecated functions g_io_channel_read(), g_io_channel_write(), and g_io_channel_seek().

g_io_channel_write ()GIOError g_io_channel_write (GIOChannel *channel, const gchar *buf, gsize count, gsize *bytes_written);

Warningg_io_channel_write is deprecated and should not be used in newly-written code.

Writes data to a GIOChannel. Members G_IO_FLAG_APPEND turns on append mode, corresponds to O_APPEND (see the documentation of the UNIX open() syscall)   G_IO_FLAG_NONBLOCK turns on nonblocking mode, corresponds to O_NONBLOCK/O_NDELAY (see the documentation of the UNIX open() syscall)   G_IO_FLAG_IS_READABLE indicates that the io channel is readable. Computer systems that use channel I/O have special hardware components that handle all input/output operations in their entirety independently of the systems' CPU(s). Giochannel Example

Parameters channel a GIOChannel   length a location to return the length of the line terminator   Returns The line termination string. Note that this means that socket-based channels cannot be set unbuffered once they have had data read from them. Close an IO channel. IBM Corporation.

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 for   func the function to call when the condition is satisfied   user_data user data to pass to func   notify the function to call when the source is removed   Returns the event source id GIOFunc () gboolean (*GIOFunc) (GIOChannel *source, GIOCondition condition, gpointer data); Specifies the type of function passed to g_io_add_watch() or g_io_add_watch_full(), which is called when the requested condition on a GIOChannel is satisfied. G_io_channel_read_chars Example This works for plain file descriptors, pipes and sockets. The current encoding is NULL or UTF-8.

UW eScience Institute member dhalperi commented May 23, 2014 So, looking at the code in question: https://github.com/uwescience/myria/blob/master/src/edu/washington/escience/myria/column/Column.java#L345 endP = startP + column.getString(i).length(); we know that column is not null, because we use it on L344 startP is not null, it's an int.
