Programming :: Include - H Files From Dir Inside Dir?

Feb 2, 2011

Basically I have a dir that contains my makefile and another directory inside this called source this holds main source files. External to these I have a couple of dirs common and drives.

In my make file I use

To include the protoypes from the headers in the folders common and drivers used by source, this works fine. However in common and drivers I use a few variables that are set in the source dir. I set these with externs inside the common and driver files. However I'm sure I should be able to set the directory path for source inside my makefile. So say I have inside source hardware.h with prototypes, I set DINCDIR = -I/Source -I../Drivers -I../CommonFiles

Then from a c file inside my common folder I say #include "hardware.h" the file should be able to see hardware.h and it's protoypes. However I get:

Is there some way I can get the extern dirs to see the source dir?

The set out is something like;

Programming :: Awk Commands Inside Of A Bash Script ?

May 4, 2011

im pretty sure this is a remedial task for many of you but im having an issue with arrays from a shell script being accessed in an awk command. im pretty good with shell scripting but i am embarrassingly unfamiliar with awk. so here's the meat of the script...


I am trying to take an input file of ip addresses and corresponding netmasks and put it into a format to be loaded onto a juniper switch. the result should look something like this.. x.x.x.x/netmask using the cidr notation. no matter what subnet is provided though, /32 always gets appended to the end of the ip even when it should be /16, /24, etc... also, the cisco part works fine so that doesnt need any attention.

Programming :: Deadlock Due To Crash Inside Critical Section?

May 12, 2011

The following two pieces of codes share printing to stdout with a POSIX semaphore /dev/shm/sem.abcd


int j;
sem_t *sem = sem_open( "/abcd", O_CREAT, S_IRUSR|S_IWUSR, 1 );
j = 0;
while (j < 100) {


If started at the same time, the first will finish in about 10 seconds; the second 20 secs.

What I want to ask is, if the first program crashes at Checkpoint A, then B will never gets to continue, then normally how do programmers avoid this kind of deadlock due to crashes inside the critical section?

Programming :: Count Specific Entries Inside A Block?

Jul 15, 2011

What I want to do is from a file having block like

8 3 0.2685416E-02
2 -1 0
21 -1 0


The first line after the "<event>" is its process-id, so I would like to have at the end a summary of how many "event" block I have for each type, ie how many

6 1 0.2685416E-02

or how many

7 2 0.2685416E-02

etc etc

I do not know in advance how many different-kind of block I will have, so it has to be a bit smart to scan the file, and make an new "summary" info for each unique type I was using something like

awk '/<event>/,/</event>/{if ($3 -eq 0.2685416E-02 ) { print $1" "$2" "$3}}' file > out

and then

grep -c "$1" "$2" "$3" but with no success since my awk commands prints all lines of each block

Suppose, that in advance I do know the $3, ie the 0.2685416E-02 which is a kind of weight

Programming :: Html Tags Inside PHP Mail Body Message?

Mar 9, 2010

Trying to write a small php program to send emails using a form. I have collected all the information in php variables and I can send the mails just fine. But I need some neat and clean formatting for the mail that is received and hence thought html tables would be nice. But all the html tags are received as plain text and not html though I have mentioned in headers content-type to be html. Any links? If anyone can put some light on it? I thought that html tags would just work fine without much issue. I have tried same with asp and it worked.

PS: I am no programmer. Just trying my hands out on some php.

Edit: I am using a php mailer class from php classes to send mails. I need some way to use an external smtp server for sending mails. I have seen pear but I do not want to use pear. It is not available on the server I am testing and it is not possible for me to install it. I do not have access to install pear and can not ask to install it.

Programming :: Command Line Works - Won't Work From Inside Bash Script

Feb 16, 2011

Writing script to create backup of file by adding datetime to file name. Basically test for file presence if there, cp with datetime then rm original cp works fine from command line but get cannot stat `full path to file': No such file or directory


Here are the errors: cp: cannot stat `~/html/CVP_dadamail/.dada_files/.logs/errors.txt': No such file or directory rm: cannot remove `...': No such file or directory

The for statement is a placeholder as I have same file to backup out of several directories. using "bash -x scriptname" -OR- inserting echos, I can see I've constructed the strings properly. Believing it might be related to the hidden directories, I tried setting the shopt "glob" options to no avail.

Ultimately I'll add the other directories to the for loop and then run this from a cron job, so if you see potential pitfalls knowing I'm headed in that direction...believe construct would be

Programming :: Does Declaring Variable Inside A Function Give An Extra Overhead On An Application

May 14, 2011

Does declaring variable inside a function give an extra overhead on an application? Would it be better to declare the variable globally and just reuse it? Example


#include <blah>
char mybuffer[2048];
int main()


The only difference is the declaration of my variable. Since myfunction() will be called many times will it add an additional overhead if it will create mybuffer[2048] over and over?

Programming :: Access The "page" Variable Inside The Script To See What Args It's Been Given?

Apr 16, 2010

I have a PHP script which will show info from 5 lines in a MySQL database, with a "next" button to show the next 5 lines and so on. Initially it'll get called with a ?page=1 in the args in the URL, and then onward I want the "next" button to link to the same script , but with a ?page=2 in the args. First of all, how can I access the "page" variable inside the script to see what args it's been given? (sorry, extremely newbie question here )

And secondly, what will the code for the "next" button look like? If the script is called "seenames.php", I want this: print "A HREF="...cgi/seenames.php?page=$page+1">Next</A> , if you get my meaning. But what will the quoting for the above line be? I'm sure I've got it wrong.

Programming :: Linking To XInput2.h Fails?

Oct 5, 2010

I have a really simple program trying to use XInput2.h, which fails on linking

#include <X11/extensions/XInput2.h>
int main(){
Display *XSession = XOpenDisplay(NULL);
int OriginScreen = 0;
int pID = 7;


I'm at a loss about what to do. Replacing XIWarpPointer by XWarpPointer and removing the pID argument solves it, but is not an option (no input ID).

Programming :: Modprobe Fails In Script / What To Do?

Jun 15, 2011

I am running into a problem with a script I have to load the proper ethernet drivers on the script start, but the modprobe command fails.

I don't know exactly what it says but I believe it was something to the effect of "cannot find (x)." Which would be fine if it did it all of the time, but if I ctrl+c out of the script and attempt to do the command manually it works.

Anyone out there know what might be going on? I've been searching google and stackoverload and here and haven't come across anyone else having this issue.

Or better yet, is there a way to have a shell script implement a .rules file for a specific instance?
