E.13.10 File-I/O Examples
-------------------------
Example sequence of a write call, file descriptor 3, buffer is at target
address 0x1234, 6 bytes should be written:
<- Fwrite,3,1234,6
_request memory read from target_
-> m1234,6
<- XXXXXX
_return "6 bytes written"_
-> F6
Example sequence of a read call, file descriptor 3, buffer is at
target address 0x1234, 6 bytes should be read:
<- Fread,3,1234,6
_request memory write to target_
-> X1234,6:XXXXXX
_return "6 bytes read"_
-> F6
Example sequence of a read call, call fails on the host due to
invalid file descriptor ('EBADF'):
<- Fread,3,1234,6
-> F-1,9
Example sequence of a read call, user presses 'Ctrl-c' before syscall
on host is called:
<- Fread,3,1234,6
-> F-1,4,C
<- T02
Example sequence of a read call, user presses 'Ctrl-c' after syscall
on host is called:
<- Fread,3,1234,6
-> X1234,6:XXXXXX
<- T02
