Well I do not wish to use IPC at this time.
So without that it is not possible, right?

Code:
 while (cgiFormFileRead(file, b, sizeof(b), &got_count) == cgiFormSuccess)
        {
        fptr = fopen("progress_bar.txt", "w");
        fwrite(b,sizeof(char),got_count,output);
        i++;
                if(i == inc && j<=100)
                {
                fprintf(fptr, "%d" ,j);
                fseek(fptr, 0, SEEK_SET);
                i = 0;
                //fflush(fptr);
                fclose(fptr);
                j++;
                }
        }

So, my ajax reads the text file after every 1 sec or so, however the data is not available until whole file is written by the CGI. Any suggestion?

       void *ptr;
       size_t size, nitems;
       FILE *stream;

       size_t fwrite(ptr, size, nitems, stream)
       void *ptr;
       size_t size, nitems;
       FILE *stream;

Description
       The  function  reads  into a block beginning at ptr, nitems of data of the size size (usually sizeof *ptr) from the named input stream.	It
       returns the number of items actually read.

       If stream is stdin and the standard output is line buffered, then any partial output line will be flushed before any call to to satisfy the

       The function appends, at most, nitems of data of the size size (usually sizeof *ptr) beginning at ptr  to  the  named  output  stream.	It
