'\" te .TH SIGSEGV 3 "17 June 2021" "Solaris 11.4" .SH NAME sigsegv \- Handling page faults in user mode .sp .SH SYNOPSIS .sp #include <\fBsigsegv.h\fR> .sp .SH DESCRIPTION .sp .LP Sigsegv is a set of functions 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: .RS +4 .TP .ie t \(bu .el o pageable virtual memory .RE .RS +4 .TP .ie t \(bu .el o memory-mapped access to persistent databases .RE .RS +4 .TP .ie t \(bu .el o generational garbage collectors .RE .RS +4 .TP .ie t \(bu .el o stack overflow handlers .RE .RS +4 .TP .ie t \(bu .el o distributed shared memory .RE .RS +4 .TP .ie t \(bu .el o \[char46].. .RE .sp .LP The sigsegv functions are summarized in this section in the following groups: .sp .RS +4 .TP .ie t \(bu .el o Global SIGSEGV handlers .RE .RS +4 .TP .ie t \(bu .el o Local SIGSEGV handlers (a handler per memory area) .RE .RS +4 .TP .ie t \(bu .el o Stack overflow handlers .RE .sp .LP The <sigsegv.h> header defines the following symbols: .sp .RS +4 .TP .ie t \(bu .el o HAVE_SIGSEGV_RECOVERY .RE .RS +4 .TP .ie t \(bu .el o HAVE_STACK_OVERFLOW_RECOVERY .RE .RS +4 .TP .ie t \(bu .el o LIBSIGSEGV_VERSION .RE .RS +4 .TP .ie t \(bu .el o SIGSEGV_FAULT_ADDRESS_ALIGNMENT .RE .sp .LP The types listed below are defined as described in <sigsegv.h>: .RS +4 .TP .ie t \(bu .el o sigsegv_handler_t .RE .RS +4 .TP .ie t \(bu .el o sigsegv_area_handler_t .RE .RS +4 .TP .ie t \(bu .el o stackoverflow_handler_t .RE .RS +4 .TP .ie t \(bu .el o stackoverflow_context_t .RE .sp .SH GLOBAL SIGSEGV HANDLERS .sp int \fBsigsegv_install_handler\fR (sigsegv_handler_t handler); .sp void \fBsigsegv_deinstall_handler\fR (void); .sp .SH LOCAL SIGSEGV HANDLERS .sp void \fBsigsegv_init\fR (sigsegv_dispatcher* dispatcher); .sp void* \fBsigsegv_register\fR (sigsegv_dispatcher* dispatcher, .RS +24 void* address, size_t len, sigsegv_area_handler_t handler, void* handler_arg); .RE .sp void \fBsigsegv_unregister\fR (sigsegv_dispatcher* dispatcher, .RS +25 void* ticket); .RE .sp int \fBsigsegv_dispatch\fR (sigsegv_dispatcher* dispatcher, .RS +22 void* fault_address); .RE .sp .SH STACK OVERFLOW HANDLERS .sp int \fBstackoverflow_install_handler\fR (stackoverflow_handler_t .RS +27 handler, void* extra_stack, size_t extra_stack_size); .RE .sp void \fBstackoverflow_deinstall_handler\fR (void); .sp .SH COPYRIGHT Copyright 1998-1999, 2002-2012, 2016-2021 Bruno Haible <bruno@clisp.org> .br Copyright 2002-2005, 2009 Paolo Bonzini <bonzini@gnu.org> .br Copyright 2008-2010 Eric Blake <ebb9@byu.net> .br Copyright 2002-2021 Free Software Foundation, Inc.
