/* This subsystem will trap SIGBUS on specific memory regions. The
|
|
* regions will be remapped to anonymous memory (i.e. writable NUL
|
|
* bytes) on SIGBUS, so that execution of the main program can
|
|
* continue though with memory having changed beneath its hands. With
|
|
* pa_memtrap_is_good() it is possible to query if a memory region is
|
|
* still 'good' i.e. no SIGBUS has happened yet for it.
|
|
*
|
|
* Intended usage is to handle memory mapped in which is controlled by
|
|
* other processes that might execute ftruncate() or when mapping inb
|
|
* hardware resources that might get invalidated when unplugged. */
