Recover help - only 2 imgs are getting recovered

Question

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{
    if(argc != 2)
    {
        fprintf(stderr, "Usage: ./recover <filename>\n");
        return 1;
    }

    char *jpg = argv[1];

    FILE *inptr = fopen(jpg, "r");

    if (inptr == NULL)
    {
        fprintf(stderr, "Couldn't open the file\n");
        return 2;
    }

    unsigned char buffer[512];
    int jcount = 0;
    char fname[7];
    int stat = 0;
    FILE *img;

    while (fread(&buffer, 512, 1, inptr))
    {

        if (buffer[0] == 0x0ff && buffer[1] == 0xd8 && buffer[2] == 0xff && (buffer[3] & 0xf0) == 0xe0)
        {


            if (stat == 1)
            {
                fclose(inptr);
                sprintf(fname, "%03i.jpg", jcount);
                img = fopen(fname, "a");
                jcount++;
            }

            if(!stat)
            {
                sprintf(fname, "%03i.jpg", jcount);
                img = fopen(fname, "w");
                stat = 1;
                jcount++;
            }
            fwrite(&buffer, 512, 1, img);
        }



        else
        {
            if (stat == 1)
            {
                fwrite(&buffer, 512, 1, img);
            }

        }
    }
    fclose(inptr);
    fclose(img);
    return 0;

}

Whats wrong with my code? Spent hours looking for a bug.

Answer 1

I was closing inptr when i was supposed to close img. So subtle! Didn't even notice it for 1 hr
