*
|
||||
* First call FSInit to initialise the file system library, then call
|
||||
* FSAddClient to initialise your FSClient structure, then you need to use
|
||||
* FSInitCmdBlock to initialise an FSCmdBlock structure for each command you
|
||||
* want to run in parallel. You must ensure the previous filesystem command
|
||||
* has been completed before reusing the same FSCmdBlock, you do not need to
|
||||
* reinitialise an FSCmdBlock before reusing it.
