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