I'm trying to write an application that can run some code when a certain memory address is read or written. My first theory was to use mprotect to remove read/write permissions from a section and then catch SIGSEGV, but siginfo_t doesn't seem to be defined. Is hooking a signal using the 'sa_sigaction' member of 'struct sigaction' supported in CygWin?
I noticed that struct siginfo_t is declared in sys/signal.h, but inside a couple of #ifdef: #if defined(__rtems__) #if defined(_POSIX_REALTIME_SIGNALS) And it doesn't have the member that I need anyways (si_addr). Does anyone know of any other ways of trapping reads/writes to/from memory regions? -Rolf Campbell Software Designer Tropic Networks -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
