List files problem

[ne0h]

Excuse me, but i use this function to get the name of the files in a directory, but I don't wan't to read "." and "..", i've try this many times but
now for this function i haven't a functionally solutions!
Can anyone help me?
And if i want to print to screen only file .xxx?

Code: Select all

int scandir(const char *dir, struct dirent ***namelist,
            int (*select)(const struct dirent *),
            int (*compar)(const struct dirent **, const struct dirent **))
{
  DIR *d;
  struct dirent *entry;
  register int i=0;
  size_t entrysize;

  if ((d=opendir(dir)) == NULL)
     return(-1);

  *namelist=NULL;
  while ((entry=readdir(d)) != NULL)
  {
    if (select == NULL || (select != NULL && (*select)(entry)))
    {
      *namelist=(struct dirent **)realloc((void *)(*namelist),
                 (size_t)((i+1)*sizeof(struct dirent *)));
	if (*namelist == NULL) return(-1);
	entrysize=sizeof(struct dirent)-sizeof(entry->d_name)+strlen(entry->d_name)+1;
	(*namelist)[i]=(struct dirent *)malloc(entrysize);
	if ((*namelist)[i] == NULL) return(-1);
	memcpy((*namelist)[i], entry, entrysize);
	i++;
    }
  }
  if (closedir(d)) return(-1);
  if (i == 0) return(-1);
  if (compar != NULL)
    qsort((void *)(*namelist), (size_t)i, sizeof(struct dirent *), compar);
    
  return(i);
}

Tanks in advance!

I've look here: http://www.cs.cf.ac.uk/Dave/C/node20.html
but not work, maybe i integrate this code in a bad mode!
Please, give me help...

Here is the code in main funciton:

Code: Select all

struct dirent **namelist;
          char dir[100]="ms0:/MUSIC/Minutes to Midnight/";
          int b;
          int a=-1;
          int n;
          pspDebugScreenSetXY(0, 4);
          n = scandir(dir, &namelist, 0, alphasort);
          int file_select();
          b=n;
          if&#40;n<0&#41;&#123;
                   printf&#40;"Directory not found or error reading!"&#41;;
                   &#125;
          while&#40;b--&#41;&#123;
                      if&#40;a!=n&#41;&#123;     
                      a++;
                      printf&#40;"%s\n", namelist&#91;a&#93;->d_name&#41;;
                      &#125;
                      &#125;


int file_select&#40;namelist&#41;
 
		&#123;if &#40;&#40;strcmp&#40;namelist->d_name, "."&#41; == 0&#41; ||
						&#40;strcmp&#40;namelist->d_name, ".."&#41; == 0&#41;&#41;
						 return &#40;FALSE&#41;;
				else
								return &#40;TRUE&#41;;
		&#125;
