read - Read from a channel
<H3><A NAME="M3">SYNOPSIS</A></H3>
<B>read </B>?<B>-nonewline</B>? <I>channelId</I><BR>
<B>read </B><I>channelId numBytes</I><BR>
<H3><A NAME="M4">DESCRIPTION</A></H3>
In the first form, the <B>read</B> command reads all of the data from
<I>channelId</I> up to the end of the file.
If the <B>-nonewline</B> switch is specified then the last character
of the file is discarded if it is a newline.
In the second form, the extra argument specifies how many bytes to
read.  Exactly that many bytes will be read and returned, unless
there are fewer than <I>numBytes</I> left in the file;  in this case
all the remaining bytes are returned.
<P>
If <I>channelId</I> is in nonblocking mode, the command may not read
as many bytes as requested:  once all available input has been read,
the command will return the data that is available rather than blocking
for more input.
The <B>-nonewline</B> switch is ignored if the command returns
before reaching the end of the file.
<P>
<B>Read</B> translates end-of-line sequences in the input into
newline characters according to the <B>-translation</B> option
for the channel.
See the manual entry for <B><A HREF="../TclCmd/fconfigure.htm">fconfigure</A></B> for details on the
<B>-translation</B> option.
