Re: [patch] MI telnet service

Hi,

This isn't a formal review, just some formatting issues:

Need double space before '*/'

Missing space after cast.

Missing space after cast.

I'm not sure about this error message.  Maybe it should be "bound", or
maybe the whole error should say something else.

Missing space before '('.

"break"s should line up with the lines above.

Extra space before ')'.

Extra spaces between '( (' and ') )'.

There are a few places in this file where a single line following an
'if' is enclosed in '{}'.  I don't know if this is ok or not, but it
looks funny to me.

This line is probably too long.

Missing space after cast.

Missing space before '(' and extra space before ')'.  The inner
parentheses are superfluous and should probably be removed.

Missing newline between comment and function.

Missing space before '(' and around '='.

Missing space before '('.

Extra parens, and missing space after '>='.

> +      if ( (buf[i] != '\n') && (buf[i] != '\r') )

Extra parens and space.  I would write this line like this:

         if (buf[i] != '\n' && buf[i] != '\r')

> +static char*

Missing space before '*'.

Need double space before '*/'

Need double space before '*/'

The indentation in this file is completely wrong.  There's also
a lot of missing space before '(' for function calls and missing
space after casts.

Cheers,
Gary
