…GH-154327) illumos sendfile(3EXT) returns the number of transferred bytes by adding it to the offset without initializing it, so the offset cannot be used to detect a partial write. Use sendfilev(3EXT), which reports the number of transferred bytes in an explicit out parameter.

it to the offset without initializing it, so the offset cannot be used to
detect a partial write. Use sendfilev(3EXT), which reports the number of
