opening multiple files sequentially

i have pulled out a whole website and it has over 100 files
(HTML).

the problem is that the hyperlinks of that file are to the internet
(having http:// .. .. /something.htm) I want to remove all that
and put just the file (for eg. something.htm)

All the HTML files have the same path to some extent, but
just the filename changes ... so i know exactly what to remove
(http:// .. ..... thing)


instead of painfully doing "Replace" for each
file in notepad and getting bald :), i want to write a simple
C program that can do this..

I know how to open files

fp = fopen("filename.htm", "a+")

but here, i have to specify the filename... and i have to do this
for 100s of files...

so how do i make a for loop or something that opens all the files
in a specified directory (say, the same directory as the EXE)
and edit them one by one ...

i hope i made my question clear ..

There are numerous ways to do this. You can even do this with simple redirection. Redirect the contents of a "ls" or a "dir" to a text file, parse it line by line for your file name. Then open that file, perform your task, close it, repeat.

Quzah.

ok.. for example, i extracted the DIR of my c file directory..
the TXT file looks like this..

now how do i pull out the file names of *.c and *.cpp files
out of this text file ?

Take about four seconds and look at one of the lines. How do you tell if it has a .c or .cpp extension? Ah hah! You look at the trailing .*

As such, the algorythm should be fairly simple:

1) read a line
2) go backwards until you find a '.' --OR-- check 2 characters from the end to see if it is a '.', if not, check 4 characters back.
3) Once you've found the extension, read the next 1 or 3 characters to see if it is 'cpp' or 'c'.
Once it is, you know that line is good. As such, back up until you hit some white space. When you reach whitespace, you know you've found the beginning of the word.
4) copy the word into a buffer

strrchr should work fine to get you to the extension.

Quzah.

PHP Code:

---

DIR *directory;
struct dirent *direntry;

directory = opendir (".");

if (directory)
{
  while ((direntry = readdir (directory)))
    if (strstr (direntry->d_name, ".wav"))
      do_stuff (direntry->d_name);
  closedir (directory);
}

else
  printf ("error opening current directory\n");
