What is the output of the following program considering an x86 based parameter passing sequence where stack grows towards lower memory addresses and that arguments are evaluated from right to left:
int i=10;
int f1()
{
static int i = 15;
printf("f1:%d ", i);
return i--;

I want to read a large (~1-4Gb) txt file with fields separated by "," and line separator "\n". Unfortunately, file contains \x00 (zero ASCII) symbols
AWK treats them as end of line + it ignores reminder of the line after the \x00.
As a simple example:
echo "\0060\0061\000\0060\0063" | nawk... (6 Replies)
hi all, i have a flat file delimited by pipe (|), and i'm loading it to sybase, the problem is when i do a select to the table of the database, the last field has new line ascii (\x0a):

Hello All,
I have a requirement where I need to replaced the hex character - '\x0D' with 2 hex characters - 'x0D' & 'x0A'
I am trying to use SED -
But somehow its not working. Any pointers?
Also the hex character '\x0D' can occur anywhere in the line.
Can this also be accomplished... (6 Replies)
Hi, everyone:
I'm new to xen.

Perl allow hex character with just one digit.
Such as \x0 \x9 \xA.
How to force to use 2 digits in m// and s///.
Such as \x00 \x09 \x0A.

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
