I also simplified the program a little bit to make it easier to debug, code:
#include <errno.h>
#include <stdio.h>
#include <string.h>
#include <ftw.h>
static inline int callback(const char *path, const struct stat *stat, int flag)
{
puts(path);
return 0;
}
int main(int argc, const char *argv[])
{
if (argc > 1 && ftw(argv[1], callback, 4096) != 0)
printf("ERROR: Failed to traverse the directory tree! (%s)\n",
strerror(errno));
return 0;
}
Command Line Output:
