C trouble with stat -

in program stat working current directory. can 1 please me this.

even though passing parameter main working current directory. , source path printing correct path have passed main.

    dir *dr;     struct dirent *cur;     struct stat fi;     long int total_size = 0;     dr = opendir(source);     char *name;     printf("%s\n\n\n", source);     if (!(dr))     {        perror("opendir()");        return(1);     }      while (cur = readdir(dr))     {         if(cur->d_name[0] != '.')         {             if(stat(cur->d_name, &fi) == -1)             {                 printf("error \n\n");             }             else             {                 printf("%s  ",cur->d_name);                 printf("%ld  ",fi.st_blocks);                 total_size = total_size + fi.st_blocks;             }         }     }     printf("\n\ntotal_size = %ld \n", total_size);     printf("\n\n\n");     return 0; 

}

cur->d_name contains file name.

to 'stat()' outside current directory,

need prefix path string.

also need check if returned struct readdir() file or sub directory.
