Ticket #7, comment 7
initial v1 3 3 This nesting is basically the same as overlapping (with the only difference is that nesting is a complete overlapping, i.e. when the file is entirely mapped twice or more). And we already have a ticket for the overlapping problem, https://github.com/bitwiseworks/libcx/issues/29. This is where it has to be fixed. 4 4 5 Note that the old MMAP implementations is free of this problem since it supports a trivial approach where each mmap call results into a new memory region so nesting/overlapping is given for free there (but this approach leads to many other problems like different mappings going out of sync etc).5 Note that the old MMAP implementations is free of this problem since it implements a trivial approach where each mmap call results into a new memory region so nesting/overlapping is given for free there (but this approach leads to many other problems like different mappings going out of sync etc).
