Hello, I'm doing homework and I'm having some problems with stat() failing.
Consider the following C program:
#include <assert.h>
#include <errno.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <dirent.h>
#include <sys/stat.h>
#include <sys/types.h>
static void scan_directory(const char *);
int
main(int argc, char **argv)
{
if(argc == 1)
{
fprintf(stderr, "Usage: dirscan path\n");
return EXIT_FAILURE;
}
scan_directory(argv[1]);
return EXIT_SUCCESS;
}
static void
scan_directory(const char *path)
{
DIR *directory = NULL;
struct dirent *entry = NULL;
struct stat statbuf;
int return_value = 0;
directory = opendir(path);
if(!directory)
{
fprintf(stderr, "Directory %s could not be opened.\n", path);
fprintf(stderr, "Reason: %s\n", strerror(errno));
/* Don't exit program, we may have been called recursively and
we want to scan what we can. */
return;
}
while((entry = readdir(directory)))
{
return_value = stat(entry->d_name, &statbuf);
if(return_value)
fprintf(stderr, "stat() failed for %s. Reason: %s\n",
entry->d_name, strerror(errno));
else
printf("stat() called successfully on: %s\n", entry->d_name);
}
return_value = closedir(directory);
assert(!return_value); /* closedir() returns 0 on success */
}
And this is what happens when I run it (first ls -al):
$ ls -al /c/cygwin/home/mikael/coding/cygwin/c++/read_directory/
total 773

stat() failed for read_directory.cpp. Reason: No such file or directory
stat() failed for read_directory.exe. Reason: No such file or directory
stat() failed for read_directory.o. Reason: No such file or directory
Why is this happening? I'm attaching the C-file and a Makefile. Perform a "$
make dirscan2" if you want to build.
