write_io_channelT_write_io_channelWriteIoChannelwrite_io_channelWriteIoChannelWriteIoChannel — Write a value to the specified I/O channels.
write_io_channelwrite_io_channelWriteIoChannelwrite_io_channelWriteIoChannelWriteIoChannel writes values to the specified transmission
channels. The channels are passed in IOChannelHandleIOChannelHandleIOChannelHandleIOChannelHandleIOChannelHandleIOChannelHandle and
can be opened and configured by open_io_channelopen_io_channelOpenIoChannelopen_io_channelOpenIoChannelOpenIoChannel, the values
are passed to ValueValueValueValueValuevalue. The parameter StatusStatusStatusStatusStatusstatus returns
for each written value in ValueValueValueValueValuevalue a quality message. The
value 0 indicates that the corresponding value of
ValueValueValueValueValuevalue could be written. Any other status value depends on
the interface. Please refer to the interface-specific documentation
