fopen: file does not exist but it does - c

Question

I want to read all files that I can find in the folder where my executable is, except the runnable file that I'm running. I code the following code but, although this list correctly the files that I have in my folder, I cannot open them with fopen because fopen prints that the file doesn't exists. If I do gedit "path of the file obtained from my program in c" then it opens perfectly from the term. Where is the bug?
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <dirent.h>
#include <unistd.h>
int main (int argc, char **argv) {
//Determining the number of files we have.
//We call to a bash command http://stackoverflow.com/questions/646241/c-run-a-system-command-and-get-output
FILE *fp, *fin;
char path[1035], cwd[1024];
int scanned = 0;
/* Open the command for reading. */
//https://askubuntu.com/questions/370697/how-to-count-number-of-files-in-a-directory-but-not-recursively
//This count soft and hard links also (I think)
fp = popen("ls -F |grep -v /", "r");
if (fp == NULL) {
printf("Failed to run command\n" );
exit(1);
}
/* Read the output a line at a time - output it. */
//Loop for each file. Be careful! if the exe is inside, it will also be counted!
while (fgets(path, sizeof(path)-1, fp) != NULL) {
printf("Reading file: %s\n", path);
fin=fopen(path,"r");
scanned = 0;
printf("caa");
if (fin != NULL){
printf("AA\n");
fclose(fin);
}
if (!fin)perror("fopen");
printf("Done! \n");
}
/* close */
pclose(fp);
printf("end");
return 0;
}

Answer 1

There are 2 bugs in your code:
when the code updates the "path" variable in your code. It has a newline at the end which needs to be corrected to NUL. This gives an incorrect path.
Something like below can be appended to your code:
while (fgets(path, sizeof(path)-1, fp) != NULL) {
len=strlen(path);
path[len-1]='\0';
Use 'ls -A1', since 'ls -F' adds a '*' in binary name:
fp = popen("ls -A1 |grep -v /", "r");

ok so just in case someone else needs a better approach, I redid the code with the comments I had. Here I let you the new code.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <math.h>
#include <dirent.h>
#include <sys/types.h>
#include <sys/stat.h>
int isDirectory(const char *path) {
struct stat statbuf;
if (stat(path, &statbuf) != 0)
return 0;
return S_ISDIR(statbuf.st_mode);
}
int main (int argc, char **argv) {
FILE *fp, *fin;
char path[1035], cwd[1024];
int scanned = 0;
int ints;
DIR *dir;
struct dirent *ent;
//getcwd prints directory where the app ran.
if ((dir = opendir (getcwd(cwd, sizeof(cwd)))) != NULL) {
/* print all the files and directories within directory */
while ((ent = readdir (dir)) != NULL) {
/*Skips . and ..*/
if (strcmp(ent->d_name, ".") == 0 || strcmp(ent->d_name, "..") == 0) continue;
if (isDirectory(ent->d_name) != 0) continue;
printf ("Reading file: %s\n", ent->d_name);
scanned = 0;
fin=fopen(ent->d_name,"r");
if (fin != NULL){
while ((scanned = fscanf(fin, "%d", ints)) != EOF) {
if(scanned == 1){
printf("%d\n", ints);
}else {
printf("Whoops! Input format is incorrect!\n");
break;
}
} //LOOP: reading file
fclose(fin);
}
if (!fin)perror("fopen");
printf("Done! \n");
}//LOOP: while opendir
closedir (dir);
} else {
/* could not open directory */
perror ("opendir");
return EXIT_FAILURE;
}
return 0;
}
