cat-like program yields a kernel panic
A simple program like a cat will trigger an oops. As I'm not able to get informations with the USB, I'm porividing the culprit to you.
#include "cat.h"
#include "builtins.h"
#include <stdio.h>
static void usage(char *execname)
{
printf("usage : %s file\n", execname);
}
int builtin_cat(char **args)
{
if (args[1] == NULL || args[2] != NULL) {
usage(args[0]);
return -1;
}
FILE* file = NULL
file = fopen(args[1], "r");
if(file == NULL) {
perror("cat");
return -1;
}
int c = 0;
while(!feof(file) && !ferror(file) && ++c < 100)
putchar(fgetc(file));
if(ferror(file)) {
perror("ls");
fclose(file);
return -1;
}
fclose(file);
return 0;
}
