hi..
i am using struct dirent to  search for a given file in a directory.the trouble is that if the name of the file is LP36-3_27FP.phd.1 it is reading it as LP-3~1.1 (and some are taking hexadecimal value) and hence strcmpi is not working.Can anyone help me solve my problem?

are you on WIN/DOS based system ?
if so you may have the DOS filename restrictions of

8 characters and another 3 for extenstion

Yeah.struct dirent reads in the dos filenames.

What compiler are you on?

You could try system("dir/b >>dir.txt"); if on windows platform.

and read from that text file.One filename on one line.

dir/b gives you the bare filenames without the size etc. details and i redirect the output to a file dir.txt

There's a set of API's for reading the LONG file names.   Basically like the regular file API's,
you just do an int 71h instead of int 21h.  See:

If you are already on a Win32 system, use the native way:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/base/listing_the_files_in_a_directory.asp ("Listing the Files in a Directory")

#define _WIN32_WINNT 0x0501

#include <windows.h>
#include <string.h>
#include <stdio.h>

int main(int argc, char *argv[])
{
   WIN32_FIND_DATA FindFileData;
   HANDLE hFind = INVALID_HANDLE_VALUE;
   char DirSpec[MAX_PATH];  // directory specification
   DWORD dwError;

   printf ("Target directory is %s.\n", argv[1]);
   strncpy (DirSpec, argv[1], strlen(argv[1])+1);
   strncat (DirSpec, "\\*", 3);

   hFind = FindFirstFile(DirSpec, &FindFileData);

   if (hFind == INVALID_HANDLE_VALUE)
   {
      printf ("Invalid file handle. Error is %u\n", GetLastError());
      return (-1);
   }
   else
   {
      printf ("First file name is %s\n", FindFileData.cFileName);
      while (FindNextFile(hFind, &FindFileData) != 0)
      {
         printf ("Next file name is %s\n", FindFileData.cFileName);
      }
   
      dwError = GetLastError();
      if (dwError == ERROR_NO_MORE_FILES)
      {
         FindClose(hFind);
      }
      else
      {
         printf ("FindNextFile error. Error is %u\n", dwError);
         return (-1);
      }
   }
   return (0);
}

Thanx for coming back so early, that was only two weeks, wow. Why aren't you using the method(s) above? You are using a compiler from stone age, so long filenames will *not* work at all.

Thats not true.system() works.It won't in the IDE.but try running your EXE from the command line or use the command line compiler tcc.

It works.
