It means you must "slide down" the remaining recipients in the vector,
and adjust recipients_count. In other words, if the count is 4 and the
vector contains structures for recipients A, B, C, D and you want to
remove B, you must change the count to 3 and move the data for C and D
so that the vector now is A, C, D.

No.

Sorry, no time to check. But you should be able to do it quite simply
using a call to memmove() to "close the gap" in the vector.
