Thanks Rudi.. this is what i was looking for. To understand your code I have gone through Sed documentation and it clears many of my doubts that how sed processes data line by line and only Pattern buffer is used to manipulate while HOLD buffer is used just keep data for future reference...Thanks again

ldns_buffer_free
ldns(3) Library Functions Manual ldns(3)
NAME
ldns_buffer_new, ldns_buffer_new_frm_data, ldns_buffer_clear, ldns_buffer_printf, ldns_buffer_free, ldns_buffer_export
SYNOPSIS
#include <stdint.h>
#include <stdbool.h>
#include <ldns/ldns.h>
ldns_buffer* ldns_buffer_new(size_t capacity);
void ldns_buffer_new_frm_data(ldns_buffer *buffer, void *data, size_t size);
void ldns_buffer_clear(ldns_buffer *buffer);
int ldns_buffer_printf(ldns_buffer *buffer, const char *format, ...);
void ldns_buffer_free(ldns_buffer *buffer);
void* ldns_buffer_export(ldns_buffer *buffer);
DESCRIPTION
ldns_buffer_new() creates a new buffer with the specified capacity.
capacity: the size (in bytes) to allocate for the buffer
Returns the created buffer
ldns_buffer_new_frm_data() creates a buffer with the specified data. The data IS copied and MEMORY allocations are done. The buffer is
not fixed and can be resized using buffer_reserve().
buffer: pointer to the buffer to put the data in
data: the data to encapsulate in the buffer
size: the size of the data
ldns_buffer_clear() clears the buffer and make it ready for writing. The buffer's limit is set to the capacity and the position is set to
0.
buffer: the buffer to clear
ldns_buffer_printf() prints to the buffer, increasing the capacity if required using buffer_reserve(). The buffer's position is set to the
terminating '\0' Returns the number of characters written (not including the terminating '\0') or -1 on failure.
ldns_buffer_free() frees the buffer.
*buffer: the buffer to be freed
Returns void
ldns_buffer_export() Makes the buffer fixed and returns a pointer to the data. The caller is responsible for free'ing the result.
*buffer: the buffer to be exported
Returns void
