Functions
luc_error_t	mtgl::snap_init ()
	Initializes the snapshot system; we don't have to do anything.
luc_error_t	mtgl::snap_snapshot (char fname[], void *buf, size_t count, int64_t *err)
	Writes contents of buffer buf to file fname.
luc_error_t	mtgl::snap_restore (char fname[], void *buf, size_t count, int64_t *err)
	Reads contents of file fname into buffer buf.
luc_error_t	mtgl::snap_pwrite (char fname[], luc_endpoint_id_t swEP, const void *buf, size_t count, off_t offset, int64_t *err)
	Stub not yet implemented since it is not yet used in MTGL.
luc_error_t	mtgl::snap_pread (char fname[], luc_endpoint_id_t swEP, void *buf, size_t count, off_t offset, int64_t *err)
	Stub not yet implemented since it is not yet used in MTGL.
luc_error_t	mtgl::snap_stat (char fname[], luc_endpoint_id_t swEP, snap_stat_buf *statBuf, int64_t *err)
	Returns info about a file.
