Gluster users - Nov 2015 - libgfapi async I/O

Hi,
     Wanted to know when is it safe to use the buffer passed to
glfs_write_async method. Is it safe to use the buffer right after returning
from glfs_write_async method or after the callback is invoked after
completion of write request.

Thanks and Regards,
rcr

No, you should not use the buffer until the callback is invoked. We try
to optimize where we can, and reducing the number of memory copies for a
write operation is one of them.
