Adding to a big char* for search engine

Hey everyone,

I've got a situation, I am building a search engine and i am trying to produce one big char pointer that points to all text that is not a tag in an html file.

I do this by reading the html file, line by line, removing tags from each line(by calling removeTag), then adding the line w/o tags to the end of my big char pointer. But alas, it is not working.

You can assume that all my functions that i call are working normally, since i've already debuged them. the error has to be where i add duplicate to the bigPtr. Any suggestions are welcome. Thanks everyone.

Oh yeah, ignore my print statements, they are just for debuging and seeing what is going where. :D

Code:

---

char* getNoTags(char* url)
{
//printf("IN GET NO TAGS");
  char contentType[ MaxLineLength ];
  char* duplicate;
  int counter;
  char* bigPtr;
  int x = 0;
  int y = 0;
  char line[MaxLineLength];
  bigPtr = new char[10000];
  FILE * f = openhttp( url, contentType );
  if ( f == NULL ) {
    exit(1);
  }

  // Print the content type
  //printf( "Content Type: \"%s\"\n", contentType );


  while ( fgets( line, MaxLineLength, f ) ) {
       
    duplicate = removeTag(line,MaxLineLength);
        //printf("%s",duplicate);
        y = 0;
    do{
      bigPtr[x] = duplicate[y];                               
         
      x++;
      y++;
        printf("%c",bigPtr[x]);
    }while(duplicate[y] != '\0');
   
        //printf("i've made it out\n");
  }

        printf("\ni'm outside everything\n");

  fclose(f);

  //bigPtr[x] = '\0';
  //printf("bigPTR: %s\n",bigPtr);
  printf("returning\n");
  return bigPtr;

}

and BTW, this is a school project, not for production.

Code:

---

bigPtr = new char[10000];

That's C++, not C.

> duplicate = removeTag(line,MaxLineLength);
Your problem is probably here. Plus if you're allocating space for duplicate in removeTag(), you're leaking memory, since you didn't free it.

Also, this is C++ code.

the unix server i compile on compiles it in C++, so i can use C++ and C for my code. I write most of my code in C, but i do use an occasional C++ command if it seems easier.

RemoveTags runs fine, i use it on other functions that work and it does exactly what it is supposed to.

And yes i know this is a memory leak, i am just trying to get this bad boy runnin so i can test my binary trees and such. I can fix that later once its runnin.

I will try and recode it w/ realloc() and see how that works out.

Any other suggestions would be awesome.

Thanks for the replies too :D

Well your "occasional use of C++ commands" makes it no longer a C issue. If any of it is C++, it all is. As such, you're in the wrong place if you choose to do it that way.

Quzah.
