* entries the provide the necessary interfaces.
|
|
* - Other interfaces are more standard and for these there probably should
|
|
* be new system calls to support the OS interface. Such interfaces
|
|
* include things like losetup, loteardown, and mkrd.
|
|
* - Other interfaces simply need to be moved out of the OS and into the C
|
|
* library where they will become accessible to application code. Such

* interfaces include mkfatfs.
