Does anybody know what is the problem?
The other posters gave you the correct reason; strict C++ does not allow
you to cast a pointer-to-function to a pointer-to-non-function. This
should fix it:
((void*)(*)(void*)) my_function
or
typedef (void*)(*PTHREADFUNC)(void*);
... PTHREADFUNC(my_function) ...

Hello,
thanks to all for the answers. I found the following (principle)
solution:
#include iostream
#include ieee754.h
int main()
{
double fp = +1.01234523e34;
union ieee754_double fp_in, fp_out;
fp_out.d = fp;
unsigned int negative = fp_out.ieee.negative;
unsigned int mantissa0 = fp_out.ieee.mantissa0;
unsigned int mantissa1 = fp_out.ieee.mantissa1;
unsigned int exponent = fp_out.ieee.exponent;
cout "out_fp = " fp_out.d endl;
cout "negative: " negative endl;
cout "mantissa0: " mantissa0 endl;
cout "mantissa1: " mantissa1 endl;
cout "exponent: " exponent endl;
fp_in.ieee.negative = negative;
fp_in.ieee.mantissa0 = mantissa0;
fp_in.ieee.mantissa1 = mantissa1;
fp_in.ieee.exponent = exponent;
cout "in_fp = " fp_in.d endl;
}
Well, I've no idea how this is portable to the RFC1832. If I study the
ieee754 header, there are #ifdefs for different endians, therefore my
conclusions: it should be. Different targets are able to rebuild the
double
from splitted components regards to their fp representation.
Maybee I should convert the uint to network byte order for transport.
With the sprintf solution I miss the precision on some case. On big
numbers
the string is very long, with the above I double only the sizeof(double)
due to
the use of unit's.
Does the sun rpc xdr handle this in a same manner ?
Thanks
Olaf

You shlould certainly do this, e.g. by using htonl() and ntohl().

Dear Madam/Sir,
Please, help my with following problem.
What is happen, if I change old ASER AP65 mother board with Pentium Pro
by new ASUS P2-99 mother board, that contains Pentium III? Old system
with Pentium Pro and ISA device works successful, new system at Pentium
III halts, then process works with old ISA device.

Michael,
I didn't go through your entire post, but I thought you might find a
document I put together helpful:
* Redhat Kernel Customization mini-HOWTO
https://sourceforge.net/docman/display_doc.php?docid=1687group_id=14191
This was composed from notes I made while customizing the kernel on my
Redhat 7.0 installation.

Subject: "Capturing" keyboard/mouse events ?
Date: Tue, 16 Jan 2001 17:50:32 +0100
Can someone give me some tips on how I can "keep track of" ALL keyboard and
mouse events that occur in X ?
- i.e. not for a specific graphic component or application, but any X event
blablabla, you get the point
is there a way of doing this that will be the same on all unix/unix-"clones"
running X ?
I also need to pipe some info about some events when they occur, preferably
through stdout ...
Thanks for any help !!

I've asked this question to no avail on the emacs newsgroup.
From an emacs standpoint I seem to be doing everything
right, so it must be a linux problem.
