C++ :: Cannot Open A Directory In Terminal

Dec 9, 2013

Taking a OS course and my professor gave us files to reference in a directory located at ~agw/class/os/share/proj3. But when I typed this into the terminal I keep getting a permission denied error message.

[lastname@erdos ~]$ ls
dead.letter Desktop Documents Downloads Music Pictures private Public public_html Templates Videos
[lastname@erdos ~]$ ~agw/class/os/share/proj3
/u/sobolev/agw/class/os/share/proj3: Permission denied.
[lastname@erdos ~]$

I've opened shared directories for this class before and had no issues.

#include <iostream>
#include <fstream>
#include <string>
using namespace std;
int OpenFile(){

C/C++ :: Open Directory And For Each File In It Create A Thread

Dec 20, 2014

I'm trying to write a program that opens a directory and for each file in directory,it creates a thread. Inside of the thread,it reads the numbers in file.(one number in one line)And then calculates the average of these numbers. I write something like this;

void *calculate(FILE *piece){
int a,k=0,s=0,ort;
while(!feof(ayri)) {
a=fgetc(ayri);
s=s+a;

[Code] ....

When I run the programme,i get lots of errors like 'segmentation error' and some stuff about pthread_create. And I don't think the 'calculate' function is right.I don't know the right way to read numbers line by line.

C :: Open New Text File With First Letter Of Line On A Certain Directory

May 23, 2013

I'm reading from stdin a line. With that line, I should open a new textfile with the first letter of that line on a certain directory. My code is the following :

Code:

int main() {
char line[BUFSIZ];
FILE *ptr_file;
int x;
while(fgets(line,BUFSIZ,stdin) != NULL){

[Code] ....

char caminho[] is the directory in which I want to create the text file and chave will be the first letter of the line in stdin.

How am I supposed to use strcat to get these two together in a string to then use ptr_file =fopen(caminho, "w");

C/C++ :: Running Multiple Terminal In Xcode

Oct 5, 2014

I am using Xcode to do c++ programming and I have a c++ code, with different input arguments. I want to achieve that in Xcode, I could run multiple simultaneous running of my c++ code. However, the current problem is that once one code finishes, its terminal window automatically closed and I do not have time to look at its result. Thus computer time is wasted. Is there a way to run multiple same c++ code with different arguments input?

C++ :: Make Terminal Screen Bigger In NCurses Program?

Jun 29, 2013

I wanted to make the terminal screen bigger in my NCurses program. Let's say if the defaults are 25 LINES and 80 COLS, I want to set them to 40 LINES and 120 COLS.

I've tried resizing all windows, but that did not work, because the actual terminal (console) was not resized. Then I found functions resizeterm and newterm, but they did not work. As far as my understanding goes resizeterm only updates NCurses information with the current configuration, while the window itself is not actually modified.

NCurses man page wrote:The function resizeterm resizes the standard and current windows to the specified dimensions

If I haven't made myself clear ( I sometimes make a mess of things... ), another example would be that I want my program to be fullscreen when I start it. Is this possible? It should be, I found a fullscreen NCurses program once, but the code was too confusing for me to understand.

Having read about things like SIGWINCH, I assume you must define a method for resizing the terminal screen yourself, I don't know where to start?

C :: Count Lines In Input And Display Output In Terminal When Program Executed After Compilation

Feb 4, 2013

Code:

#include <stdio.h>
main() {
int c, n1;
n1 = 0;
while ((c = getchar()) != EOF)
if (c == '')
++n1;
printf("%d", n1);
}

I have a more complicated program I'm wishing to have display the output, however, to save some time I'm using an example of a shorter version. count the lines in input and display the output in terminal when ./program is executed after compilation. To count and compute lines, words and within arrays.

C++ :: How To Protect Entire TMP Directory

Mar 13, 2014

The general design of my app work-flow:

My application is processing a large amount of data (approx. 50 - 100 GB of txt data). given the machine regular user usually has, my app is writing some tmp data into a local tmp directory. and this is working just fine until users get comfortable with my software and start changing that content of local tmp dir (while the program is running). which does not give any problems like crashing a program if handled at the right time but produces wrong results in the end. now this is not my problem but i would still like to somehow restrict users from even peeking into the tmp dir. I am just tired of getting emails saying my software is cr.... (maybe it is but i don't think it is because of that)

So is it possible to somehow encrypt the entire dir so that only the program has access to it . it would be even better if the dir could look as some encrypted index file so that when user sees the warning :

"tmp" may be a binary file. See it anyway?

C :: How To Get User Home Directory

Oct 20, 2014

I want to obtain the user's home directory. I know it can be done with getenv("HOME"), but if I'll inspect the value of the enviroment variable HOME, it might work when I run it now, but it won't work on Windows, since windows uses HOMEPATH to save the user's home directory.

Is there a different, more cross-platform way to do it?

C :: Merging All TXT Files In A Directory

Dec 6, 2013

I'm writing a program to merge all .txt files in a directory. I had the code working and then made small change. It started crashing and I couldn't get it back to working.

Code:
#include <stdio.h>
#include <stdlib.h>
#include <dirent.h>
#include <unistd.h>
#include <string.h>
#include <sys/stat.h>

[Code] ....

It's crashing around the

Code: while(!feof(in)){ .

If I comment that section out, the code still works. But, I know that portion of the code works to copy text from one file to another! It's actually from the Schildt complete C reference and I have tested it several times on it's own.

C :: Using Process ID As The Name Of File Directory

Jan 31, 2015

I need my Unix program to generate a directory with a format like this: "hinesro.<pid>". I have some code that mostly works, except for the directory ends up with a question mark on the end, like this: "hinesro.12345?". I need it to just display the directory without this question mark. Here is my code:

Code:

// Using headers sys/types.h, sys/stat.h, unistd.h, and stdio.h
int pid = getpid();
char prefix[] = "hinesro.";
char fileName[0];
sprintf(fileName, "%s%d
", prefix, pid);

C++ :: DLL Search Directory Order

Aug 29, 2013

I was working on a program. "hey if this program were to be published it would be bad for people to see all dll files are in the exe directory"....

So I wondered if there is a way to make compiler see a folder in the same directory with exe file which holds all dll files?

Also look at some programs and saw they have a dll folder which holds dll files....

C/C++ :: Scan A Directory Recursively

Dec 19, 2014

I'm writing a C++ module that is meant to recursively scan a directory and I'm curious what yall think of my strategy.

The program is a music player and so I'm trying to make the directory scanner as lightweight and efficient as I can. I've decided I want to scan the files in two passes- first I just want to get a list of all music files that are found in a directory/subdirectories and then I want to process the list and search for id3s/other tags.

As I'm a scanning the directory, I've decided to store the temporary list in a linked list where each node is containing an array of 100 strings. I did this because I obviously don't know how long the list will be and I from my understanding of the C++ vector class it basically just makes over sized arrays and moves them when it runs out of space. That sounded rather clunky to me, as did a traditional linked list.. I didn't see the point of allocating memory that many times in a row.
