I'm in the process of debugging and compiling about sixty FORTRAN 95 programs and could use a little bit of your help before my brain is fried and fingers are cramped. Thanks for your time!
I receive the following errors:
Here is my code:
I'm trying to get the width of a string in pixels this way:
Display *disp;
int len;
disp = XOpenDisplay(0);
font = XLoadQueryFont(disp, desc );
[code]....
I'm getting negative numbers as the the pixel length, eg -7275
A couple of days I started using latex and have still one question about the table width. My table is too wide for a page. How can I adjust it so that it fits on the full width of a page? Can I use a command or do I have to specify each column widths by hand?
My table looks like this;
I did try several commands likeextwidth, esizebox, setlength but didn't found the solution yet.
I use ioctl to get the cosole window size (the SSH window).
I use the following code:
When I debug on linux pc, it gives me the correct window width. But after I try it on router (this is my enventual place where my code shall run), ioctl always give me 0 width, that is, numberOfColumnsOfTerminalWindow == 0. but the returnValue is 0 which means that the function call succeeds.
In C++ as subjected, can anyone throw me some light on how I can generic-ly format an integer value of 1 to a string value of 0001? 11 to 0011? and 111 to 0111? simply by just appending 0 in front and limiting the length of the string to 4?

I've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.
[Code]....
One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?
Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.
I Just got a Removable Hard drive! Now I need to format it because I need it to hold more then 4 GB file sizes. What format should i used. I'll only need compatibility with Other LINUX computers. So should i use NTFS, BTRFS, or EXT4? How would i take ownership of the backup drivers file system and not ROOTS permissions

I need to creates string suffixes out of a Reference string. for eg. suffixes of abcdefg will be

create an array of pointers to point to the first few characters and then use that pointer to print the rest of the string.But when i print using the pointer i get GARBAGE values! shudn't std::cout<<ptr[w] print the string following the char it is pointing to? why do i get garbage values?
So if I'm given a location of a file like:
How can I just take the type of the file at the end? I know I can use strrchr() for a period to get the pointer to the period just before file type. Is there a build in string function that will just take the rest of the string from a certain point on forward in the string? I know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.

I wonder how CLI applications know the width of the terminal. For example, how does ls know how many columns to use?
How do package managers like pacman know what length to make the download progress bar?
Also, how do they redraw the progress bar in the same line?
I've been given a custom-made string class which handles string, wstring and bstr. It has a number of methods and assignment operators to convert to and from different types. The app I work on compiles happily in VS6 and VS2008, but when trying to compile in Redhat (version 4.1.1 in Redhat 5.0)

I have the following two type of strings1: A/D2: A/C/DI am trying to write a subroutine to check whether all of the letters in string 1 appears in string 2. If yes, return true. If not, return false. In the above example, all the letters (A and D) in string 1 are also present in string 2, so I return true.

The error I got is
Code:
The libidata.so.42 is there in that folder. I guess the file might be in a big endian. Is there a way to check if the libidata.so.42 i have might be a big endian format, rather than little endian?
If my guess is incorrect, This is a c++ code on fedora x86 machine.
How do I find out how many characters fit into a terminal window horizontally and how many lines the terminal window is high (i.e. how many rows and columns are visible - the width and height)? I am using c++ and Linux Mint 8 - Gnome.
View 8 Replies View RelatedI am trying to write commands that extracts the height and width of a video file via ffmpeg. I have the following working so far:
This gives the following answer in widthxheight format with an extra , 720x480,
How can I instead run 2 separate commands that give me height and width separately? I want some command to give me 720 and another command to give me 480 and I dont need the x or the ,
If you need to know this is what ffmpeg -i videofile.mov 2>&1 gives as output

I need to manually convert an string ( like with echo ) to a DES crypt format to be inserted inside a /etc/shadow file, does anybody knows how can I do that?
Maybe there are some little tool that could handle that operation, well.. I don't know, hope someone can give me a hint on that.
I use ioctl to get the console window size (the SSH window). I use the following code:
