This library provides fake replacements for the BTI and PMT syscalls for the purpose of testing driver code in an unprivileged environment. It works by defining strong symbols for the following system calls:

• zx_object_get_info()
• zx_bti_pin()
• zx_bti_release_quarantine().
• zx_pmt_unpin()

The library exposes methods for creating and destroying fake BTI “handles” that are compatible with the fake BTI syscalls. It is not safe to use any other handle operations on the fake BTI and PMT handles.
