Programming in C.I have two char arrays.char buf1[1024];char buf2[1024];Aren't buf1 and buf2 also pointers?I read in 1024 bytes into buf1 which contain about 300 bytes of characters with newlines. The data is basically a few English sentences. I'm trying to scan buf1 for newlines and then stop at the 1st newline and copy the rest of the data from that 1st newline into buf2.So I run a for loop to look for that new line.
Code:
for(i=0; i<1024;i++) {
if((strcmp(&buf1[i], "

Line 43 points at the snprintf() command.I think the error has to do with the function being virtual and the const after the function definition, however although I have been looking really hard I have not being able to find the reason nor the solution to the problem.
One workaround that I know is moving the block of source withing the virtual function, in the constructor, however having read around (boost library exceptions tutorials) it specifically said that formating of errors messages should not take place withing the construction of objects because we are risking throwing an exceptions and messing up the flow order.
i define variable of type char (range -128 to 127). when i tried to print the value after assigning a -ve value to it it displaying a +ve value of that -ve value(256+value).

View 8 Replies View RelatedI'm doing an assignment for school, and while we have not yet learned regular expressions, my teacher would like us to use AWK to append text to certain lines in a file. What we've had to do is creating a listing of all links and directories in the /etc folder and place them in a text file. From this, we were to cut the first field (Permissions) and the ninth field (filename) and create another text file. Now the part that I'm struggling with is this and I'm not sure if I should be using sed or awk. We're supposed to ADD the text "DIR" to the beginning of any line that is a directory, and "LNK" to any that is a link, like so:
DIRdrwxr-xr-x redhat-lsb
DIRdrwxr-xr-x rhgb
LNKlrwxrwxrwx rnDIRc.key
DIRdrwxr-xr-x rpm
Obviously, I realize that the first character in the permissions denotes what sort of file it is, hence when I created my text file I used
ls -l | grep "^d" > file.txt
and
ls -l | grep "^l" >> file.txt
I'd like to learn how to properly do this, but struggling through pages on the internet hasn't been helping, nor has the --help command. Therefore, while I would like the answer, I'd also like to know what the heck I'm doing For example, I know I could delete lines with regex using d/[STUFF I WANT TO DELETE]/g (To get rid of all occurences) and I can substitute using s/foo/bar But I'm unaware of anyway to ADD text upon certain occurences, let alone two different circumstances.

eed to make a script to append a line to the bottom of multiple files (only certain files, but 100's spread over directories).Doing a find replace inside multiple files is easy, I use the followingfind /base/dir -name "*.txt" -exec perl -pi -w -e 's/FIND/REPLACE/g;' {} ;So I tried doing the followingfind /base/dir -name "*.txt" -exec echo "Append this" >> {} ;However this just appends all the text into a file called "{}". Whereas {} should be replaced with each file that's found.
View 1 Replies View RelatedMy laptop has sat in the same area for days, I've noticed that in Ubuntu I get a real low signal and can barely connect for a minute and on Windows I get like 3/5 bars. I don't understand what's going on. Is it a driver issue or something?My wireless card is Realtek RTL8187B and using the latest Ubuntu as of today.But just so everyone knows, I have google'd and search around for a few hours. I've seen many different types of problems that just wasn't like mine. Lots of people can't even get theirs to work and some people use different types of drivers. But Ubuntu detects my wireless card fine, I'm just having a signal strength problem. Because the Windows on my laptop has a much stronger signal as stated above.

Since I installed Debain Squeeze with KDE (for more than a month), there is something I cannot explain to myself. 5-10 minutes after bootup my hard disk begins to work very intensely. Then, after 2-3 minutes it comes back to its normal operation. Using "atop" I found out that the first process that squeezez my HDD is "find". Then, a little bit later, mount.ntfs-3g appears. Both do what they do, then exit and everything's back to normal. What I suppose, is that that something is searching, first on the Linux partitions, then on the ntfs partitions.
Does anybody know what is this phenomenon related to? Or at least, how could I find out. Ah, and to avoid some basic troubleshooting questions: I have 3 GB of RAM, so no swap is needed. And I repeat: it's find and mount.ntfs-3g that use the HDD.
I've got the b43 driver and firmware installed, and the system comes up fine, but the max throughput on the wlan0 is about 100Kb/s. My laptop and iwl do about 2.5Mbps from the same location in the house. The signal is plenty strong:
wlan0
IEEE 802.11bg ESSID:"sar2"
Mode: Managed Frequency:2.422 GHz Access Point: 00:23:69:22:5C:00
Bit Rate=36 Mb/s Tx-Power=20 dBm
Retry min limit:7 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=61/70 Signal level=-49 dBm Noise level=-57 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Is this expected from the b43 driver and a bcm4318? I was hoping for much better throughput. Also, I tried the broadcom-wl driver, but it doesn't seem to recognize the card. It looks like it's not supported from their site, only the 4311,12,21,22 were listed, although I see posts where other people claim they are using it with a 4318?
