How can I allocate arrays or structures bigger than 64K?..

Answer / s.v.prasad reddy,lifetree

Generally using the malloc() function maximum we can
allocate the 64K memory.

If you want to allocate the memory larger than 64K then you
have to use the farmalloc() memory management function.

And one more important thing is ,Once memory is allocated
by the farmalloc(),then to free that memory we need to use
only farfree() fuction.We can't use the free() fuction to
free that memory.
