bigseek - test 64-bit seek positions
bigseek tests manipulation of seek pointers past 2 31. It is somewhat limited in what it can do, because neither SFS nor emufs supports files larger than 232 bytes; but it can still seek around and check that the resulting seek position is reported correctly.
bigseek uses the following system calls:
bigseek should work once you have implemented the basic system calls. Until you implement remove, it will not be able to delete its test file; this is merely untidy, not a problem.
