The *trivfs library*, which is declared in ``, does most of the work of implementing this kind of translator. This library requires the [[iohelp|libiohelp]] and [[ports|libports]] libraries. Using `libtrivfs` is not the only way to implement such a single-file translator, but is a convenient abstraction: the library hides a lot of low-level stuff and you just have to provide a number of call-back functions and symbols in order to get a functioning (for file I/O, etc.) node in the file system. # Further Reading * In the *[[The_GNU_Hurd_Reference_Manual|reference_manual]]*: . * In the *[[Hurd_Hacking_Guide]]*: .
