C++ (Cpp) sendx Examples

Example #1

    //printf("<< %" PRId64 "\n", now) ; 

    uint64_t then;

Example #2

/*
 * Internal character-adder.  It tries to keep the number of sendx()
 *  calls down by looking at each character but only doing the output
 *  when it has to escape something; ordinary text gets saved up in
 *  chunks the start of which is indicated by *breaker.
 * c is the character, next points to the UTF8 representing the next
 *  lastsP indirectly points to the UTF8 representing the
 *  character, breakerP* indirectly points to the last place genx
 *  changed the UTF8, e.g. by escaping a '<'
