Hi there, I am writing C++ code in Linux (2.6.18) using pthreads. glibc 2.5. gcc 4.1.2
1) I understand that signals SIGFPE and SIGSEGV are sent to individual threads while SIGINT is sent to the whole process. How do I find out what signal is thread specific and what signal is process wide. How does the OS/glibc determine which thread should be served the signal? 2) I would like to translate SIGSEGV or SIGFPE to an exception in the program so that it can be caught at higher levels. Is there a default option to convert a SIGSEGV to an exception? For my tests, I provided a signal handler for SIGSEGV/SIGFPE that throws an int exception and it works. Is it legal to throw exceptions in signal handlers? Is there any limitation on what kind of object can be thrown as an exception? Could someone help me understand the rules in this space? 3) Could someone point me to a sample to print the stack trace when an exception occurred? Thank you. Sincerely Sudhakar
