|
GNU libsigsegv is a library for handling page faults in user mode. A
|
|
|
|
|
page fault occurs when a program tries to access to a region of memory
|
|
|
|
|
that is currently not available. Catching and handling a page fault is
|
|
|
|
|
a useful technique for implementing pageable virtual memory,
|
|
|
|
|
memory-mapped access to persistent databases, generational garbage
|
|
|
|
|
collectors, stack overflow handlers, distributed shared memory, and
|
|
|
|
|
more.
