2 Error Handling
2.1 Filesystem Exceptions
Provides an exception structure and utility functions.
| ||||||||||
The exception type used to signal 9P errors, both from backends to
the generic server code and from the client code to frontends.
Raises an exception of type exn:fail:filesystem:9p with
the 9P error name ename as its message.
2.2 Error Messages
Provides error messages for standard POSIX.1 and ISO C99 error
conditions. 9P transmits error conditions as strings over the
network, but most operating systems use numeric error codes in
their APIs. Therefore it is useful to help protocol conversion
code and use well known messages.
