I have my libraries in ../../lib location
and when i try to compile :
gcc -O9 -I ../../include/ -L ../../lib/ -o test test.c thr.o -lm -lthread
I get :
gcc: error: thr.o: No such file or directory
obviously the problem is the library path location but my obj is there
ls -al ../../lib/ | grep thr.o
-rw-rw-r-- 1 xxxxxx xxxxxx 23544 Aug 12 23:03 thr.o

I need to develop an application in VC++ that will take .WAV files as an input and identify if there is a Gun shot in that wave file. WAVE file with gunshot must be having certain paramaters like frequency, bit rate etc which I don't know right now. But is there a way in VC++ to develop a program that can recognize gunshots by comparing that .WAV file with certain parameters?
View 3 Replies View RelatedI have a std::vector of short ints that I need to write to a specific location in a binary file (without using .NET code). To that end, I wrote up this code:
Code:
ofstream fileStream (filePathString, ios::out | ios::binary);
int curPos = 2821;
fileStream.seekp(curPos);
int iter = 0;
while (iter < 1024*1024){
char bytesToWrite[2];
//Low byte
bytesToWrite[0] = LOBYTE(dataVector[iter]);
[Code]...
The code runs without crashing, but when I look at the file afterwards in a hex editor, every byte (even those outside the range I thought I was writing to) are replaced with 00. I suspect I'm missing something in my understanding of file streams. Did I write that code correctly? Seekp does move the pointer over the next byte to be overwritten, yes? Am I getting a memory leak somewhere?
I'm having trouble opening a file from a specific location.
#include "maidcafe.h"
....
char directory[80] = {"C:UsersPublicDocumentsAnime NotesTransaction"};
char code[20];
printf("Enter file name");
gets(code);
strcat(directory,code);
system("start "" %s",directory);
i thought this would work, but it didn't xD. I got an error
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?
My project is to get a file from a designated location in my computer and not just read, but grab the values from the user and make a count, sum, and average calculation of the numbers in my code. I am using the fstream library and I am trying I did do it, I got the values and calcualated them, however I want the values to be accessed from maybe my desktop or my drive, I want to know how to manipulate my code to get a path like C:UserDesktop and maybe executed from the path input or given. I dont know if this is possible, or easy to do. ALso I did copy some of this code from my teachers examples and I dont know exatly why the variables have to be initilized at zero, and I would like to know a little more on the Bitwise right shift breaker used in line 20 something.

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];

I would like to copy one bmp file to another using plain fstream (none 3-rd party library). I've managed to come up with something but I keep getting error:
Unhandled exception at 0x504A3442 (msvcr120d.dll) in ConsoleApplication1.exe: 0xC0000005: Access violation reading location 0x00380000.
when i try to write the content of the bmp files not the header, namely error occurs in this line:
Code : ofs_differential.write((char*)&picture, (bfh_warm.bfSize - bfh_warm.bfOffBits));
Also i am not sure if i am doing it in a right way, meaning that even after solving this error i will copy the bmp file successfully.

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?
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

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

View 3 Replies View RelatedI'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;

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.

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() {

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

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");
I have two questions about C programming here :
1. I want to make a file in the program directory that can't be deleted by user out of the program make that file.for example if I make a file named "123.xyz" by the program named "text.exe" and then exit test.exe ,if I tried to delete the file 123.xyz I faced the error and I could not do it but by the test.exe program that make that file.
2. I heard about a function called "Parbegin()".any way i want to know is there any possible way to run two or more functions of a file.c together,like the parbegin function did an do in OS?
I know how to open a specific files by using

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.
