If this program does *not* use fork() to create additional processes, it
should be no really problem to adapt it to sctplib's socket API. However, our
sctplib is a userland implemenation and the socket API relies strongly on
threads. That is, comparing the performance of kernel TCP and userland
sctplib + socket API, the result will be that kernel TCP is much more
efficient (much less CPU load for the same transmitted bandwidth; I assume
that is what you want to examine).
