i did not try obstacks yet, will have a look at them. what bothers me
at the moment is that mremap() is not a standard and that it operates
strangely to me:
ENOMEM
The region is private writable, and insufficient virtual memory is
available to extend it. Also, this error will occur if MREMAP_MAYMOVE
is not given and the extension would collide with another mapped region.
i thought that mmap'ed space is only virtually aligned. possibly it's
better to write buffers oneself? the posix interfaces look strange to
me. they seem halfhearted and weirdly incompatible. consider a file
that is growing. how to best remap it?
