I am looking for least expensive options. No buffer copying, etc.
Peek or search API will take us to the spot, but, any buffer iovec writes will result in undefined behavior, as per documentation.

Hi,
If you don't want to use pullup, you can use something like (but only
if you data at the beginning of the buffer, otherwise it is like
pullup):
evbuffer_remove(buf, data, bytes);
data[1] = 'x';
evbuffer_prepend(buf, data, bytes);
Or
evbuffer_ptr_evbuffer_search() # but be aware of continuous
But I'm not sure that this is optimal though.
Azat.
