[olsr-dev] [PATCH] Improvements in dot_draw plugin

[Bernd Petrovitsch]

The attached patch removes lots of duplicated stuff by adding a
ipc_send_str() function.
Furtehr a few typos are corrected and a function and several variables
were made "static".
It is against 0.4.9.

The open questions are:
- Do you actually appreciate such patches?
  And in that format?
- There severe problems there also: The use of sprintf() is dangerous
  since the function doesn't know how long the buffer.
  The obvious fix is to replace it (unconditionally) with the - now
  common on glibc systems - snprintf() (which I could do). The question
  is if non-Linux-OSes have a problem with such a fix.
  I'm also not a friend of strcpy()/strcat() for the same reason.
  And BTW strncpy()/strncat() have the problem that they do not
  guarantee a terminating \0 character in the string.
- Do you want more such "cleanup" patches?
  And can they be done so that *BSD and Win* do not suffer from
  Linux-isms I'm probably introducing?

	Bernd
