Subject: [9fans] libbio and large files
Topicbox-Message-UUID: a95674c8-ead3-11e9-9d60-3106f5b1d025

This question may be more applicable when addressing p9p on other
systems:

I'm seeking a little clarification about Bopen and reading through
files larger than (2^31 bytes).  Other host systems where p9p works
(very well I might add) tend to have different definitions for off_t
depending on 32/64 bit support (some require off64_t while others do
contortions around redefining off_t depending on the joy of compiler
flags, both leading to other incantations that may require
orthodontia), how does one go about ensuring that their host OS does
properly access large files properly when using libbio?

Also--shouldn't binit.c:125 in p9p be updated to the changes found on
sources?

cpu % history -D binit.c
