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++ :: How To Save File Directory To Text File Using Ofstream

Jul 22, 2013

I'm having a little problem with std:fstream - in my program, the user selects the location of a file which I want to remember. So, I have something like this:

Code: std::string fileLocation;
//Code here creates an 'open file' dialog box which lets the user choose which file to open.
//The string 'fileLocation' now contains the path to the chosen file.
std::ofstream prefs("prefs.txt");
if (prefs.is_open())
{
prefs << fileLocation;
prefs.close();
}

This works fine if the file chosen is in the same directory as the program, however, if they try to choose a directory outside of where the program is kept, it saves the text file into that directory instead of the same one as the program. So, it looks like outputting a directory into an ofstream actually changes the location to which the file is saved.

Is there a way to save the file directory to a text file using ofstream and still have the text file save in the same directory as the program?

C++ ::  Read Only The Oldest File From Directory

Jan 5, 2013

I'm quite new to C++ and got a problem of reading some files from a directory. All files is pure text, and I have no problem in reading these.

My problem is that I always have to read the oldest file without knowing the filename, and then move it to another directory and so on. Is it possible to use the timestamp instead of the filename to access the right file - read it and then move it to another directory?

C++ :: Input File Directory From The Console?

Aug 19, 2014

Convert this code into one where you can input the file directory from the console?

#define WIN32_LEAN_AND_MEAN // prevent windows.h from including "kitchen sink"
#include <windows.h>
#include <iostream>
#include <string>
using namespace std;
int main()
{LPCSTR Application = "C:Program FilesWindows Media Playerwmplayer.exe";
// Media file extension must be provided
// Paths are quoted

[Code] ....

This code works but the directory can only be changed from the code not the console.

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# :: Writing To Text File And Uploading It To Server Directory

Dec 25, 2014

I want to write a single line to a file and upload it as a .txt file to a server directory . I know the traditional way to upload a local file to a server

public bool ftpTransfer(string fileName){
try {
string ftpAddress = "test.com";
string username = "test";
string password = "test";

[Code] ....

is there anyway to change this so that I can write the contents of the file through the program and upload it directly without having a local file?

C++ :: Checking Existence Of A File In A Directory Using Stat Command

Nov 5, 2014

I am using stat command to check the existence of a file in a directory.

The directory is having some 10K files. I feel the stat() call is expensive as i do not need the structure to be populated.

I want only the existence of the file.

Is there any other alternative faster way to do this in C.

C++ :: Intermediate File Multi-process Safety?

Jul 21, 2012

I have a compressor that takes a file and first compresses it to an intermediate file "temp.lz", before compressing it to the final format. Immediately after that the file be removed by calling c's remove(char*). The problem I am afraid of is if calling this compressor from different processes is safe because of the intermediate file created which has the same name for all. (say temp.lz). Will I have problems when callinga sytem call from different process something like: system ("compress -i test.txt -o test.z") ?

I was thinking of rewriting the compressor to avoid the use of the temporary file but that is a bit awkward. I just need to use a temporary stream (file) different for each process to avoid race conditions.

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?
