o Handle a case where an empty line doesn't exists as a delimiter of

|
each packet. If the output is sent to a control blade and
|
|
|
|
displayed as an event log, there's always an empty line between

each packet output, but it may not be true when it is an PE

output.
|
|
|
|
|
|

|
o Some telnet client on Windows may put in a line break at 80
|
|
|
|
columns when it save the session to a text file ("CRT" is such an
|
|
|
|
example). I don't think it's a good idea for the telnet client to
|
|
|

do so, but CRT is widely used in Windows community, I should
|
|
|
|
take care of that in the future.

addition to an error code, an error info string, for
WTAP_ERR_UNSUPPORTED, WTAP_ERR_UNSUPPORTED_ENCAP, and
WTAP_ERR_BAD_RECORD errors. Replace the error messages logged with
"g_message()" for those errors with g_strdup()ed or g_strdup_printf()ed
strings returned as the error info string, and change the callers of
those routines to, for those errors, put the info string into the
printed message or alert box for the error.
Add messages for cases where those errors were returned without printing
an additional message.
Nobody uses the error code from "cf_read()" - "cf_read()" puts up the
alert box itself for failures; get rid of the error code, so it just
returns a success/failure indication.
Rename "file_read_error_message()" to "cf_read_error_message()", as it
handles read errors from Wiretap, and have it take an error info string
as an argument. (That handles a lot of the work of putting the info
string into the error message.)
Make some variables in "ascend-grammar.y" static.
Check the return value of "erf_read_header()" in "erf_seek_read()".
Get rid of an unused #define in "i4btrace.c".
