The printer is working under RH6.1 and Deskjet 670 filter (GhostScript
5.10) and Is seen as a 300dpi postscript printer
I still haven't figure out how to work with (in italin is fronte/retro)
capability of that printer, nor with higher resolution.
Please infor me if you find a better way to use this printer.

Too bad I had him killfiled already, I'm sure that would've been
a very entertaining and amusing post =)
It's nice how he has to put it on nearly every linux-related

don't froth at the mouth like those in COLA, or Mark as a shining

OK, wanker. I don't know the person in question and don't care about him,
but I have to agree with his description of *.advocacy lusers in general
and you in particular.
Feel free to run DejaNews search on me. Additionally, you can grep the
kernel source for (AV|Al Viro).
Now, fuck off and die, subhuman. Preferably somewhere far away from c.o.l.d.s.

My question is to allocate a block of continuous physical memory from
the kernel for my driver's DMA.
I've heard that there is a way in patching the kernel, but I failed to
find it in internet by myself. Could anybody help me?
And whether there's a normal way (by kernel API) to solve it?
Any suggestion is welcome.

Neat. I never realized POSIX defined a testing framework.
Does DejaGNU run easily on Windows? (using Tcl and Expect)

I simply posted a followup article (with a new Subject line)
in the same newsgroups to which Chad Myers sent his original
article (quoted in full below), and to which he sent his
reply (quoted above). However, I've redirected followups
for *this* article to the advocacy newsgroups only.

Subject: converting htond (host to netwrok double)

==============E01B1F1C253BAF01AFFB97E9
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit
Hi,
I want to implement host to netwrok double, here is how I was trying to
do
it
void htond(double in, double *out)
{
char *i, *o=(char *)out;
int idx;
i = (char *)∈
if(getEndianness() == LITTLE_ENDIAN)
{
for(idx=0; idx < sizeof(double); idx++)
{
o[sizeof(double) - 1 - idx] = i[idx];
}
printf("o = %lf\n", *((double *)o));
}
else
{
for(idx=0; idx < sizeof(double); idx ++)
{
o[idx] = i[idx];
}
}
}
But when I print the value of the double value returned by the function
on a Little Endian system (ex Linux on ix86 machine) it always prints
0.000000000. But if the print the individual bytes of the
double they seem to be in the netwrok byte order.
I also tried having a union, but it gave the same result.
union overlap {
double out;
char o[8];
}cpy;
Can you please tell me how can I achieve htond, if there is some
other way.
TIA.
Regards,
Sudhin.

You should use unsigned char for this purpose.

The else part here is a little bit inefficient, since it's just doing a bitwise
copy of the object. It can be replaced by a straight assignment.
Morever, the endianness can be configured at compile time:
#ifdef LITTLE_ENDIAN
/* reverse the bytes */
#else
*out = in; /* presto! */
#endif

Network byte order is big endian. So the little endian machine is interpreting
the reversed bytes as a double value.
On any given host, you must first unpack the value by running it through the
opposite function ntohd() (which can just be an alias for htond()).
In other words, the sender uses htond() to swap the value into network byte
order, which the receiver must undo by using ntohd().
Anyway, your whole approach will fail when the two machines don't share
the same floating point representation. To do this right, you need
an interface like:
/* Compute network format. Returns 0 if the value is out of
range of the network representation. */
enum {
MARSHAL_DOUBLE_OK,
MARSHAL_DOUBLE_PRECISION_LOSS,
MARSHAL_DOUBLE_OUT_OF_RANGE
};
int marshal_double(double in, unsigned char *out);
int unmarshal_double(unsigned char *in, double *out);
The marshal function should break down the value of the double and
represent it in some canonical format. The unmarshal function
knows how to decode that format and compute a value of double from it.
The ANSI C <math.h> functions ldexp() and frexp() might be useful
in the implementation.

tee should be in usr/bin.
If not the following basic program should work:
#include <stdio.h>
main(void)

FILE *oFile;

I'm porting a Digital Unix driver to Linux platform.
I found that in Digital UNIX,there're a lot of 'sp' function,such as
spl(),splimp() and etc. But I don't know whether to map them in Linux.
I'm green in Linux kernel programming and found few books on it around
me, so I'm eager to make friends with you all. Please give some
suggestion,whether on this problem or how to get the answer by myself.
Thanks.
