I have questions about using file system for L4/fiasco & L4re.

I tried to convert applications using file I/O to L4 environment but I failed.

So I realized that I need to use file system in L4/fiasco, but I couldn't find any documents about it.

I have two questions.

1. How can I put root file system on L4/fiasco? Are there any references or documents that I can refer?

2. How can I verify whether file system is working or not. Are there any libraries for L4 to use file I/O?

In L4Re every application has its own filesystem and others are mounting therein. The most prominent is the rom/ filesystem which contains all the loaded modules and is available to all application read-only. So typically when an application needs files they can be loaded as a modules and are then available under rom/. For using it it's as simple as open("rom/file.xyz", O_RDONLY), read, mmap, etc. Adam -- Adam adam@os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/
