Hi,

I have written library in c++ for c++ application. Here, data exchange between library and client through structure. This structure has 20 members ( strings, integers, reals, pointers).

In some flows, library needs few members should get filled in the structure. for ex, application filled 3 integers information and passed to structure. But, in memory, whole structure is occupied.

I think, If library provides functions for every combination, then it would end up with lot of functions. I want to avoid that.

How to optimize data exchange between client and library? ( number of members may be filled sometimes 1, 2, 3, .. 20)

Thanks.
