Marcel Moolenaar 91078fca0c sigset_t change (part 3 of 5) ... ----------------------------- By introducing a new sigframe so that the signal handler operates on the new siginfo_t and on ucontext_t instead of sigcontext, we now need two version of sendsig and sigreturn. A flag in struct proc determines whether the process expects an old sigframe or a new sigframe. The signal trampoline handles which sigreturn to call. It does this by testing for a magic cookie in the frame. The alpha uses osigreturn to implement longjmp. This means that osigreturn is not only used for compatibility with existing binaries. To handle the new sigset_t, setjmp saves it in sc_reserved (see NOTE). the struct sigframe has been moved from frame.h to sigframe.h to handle the complex header dependencies that was caused by the new sigframe. NOTE: For the i386, the size of jmp_buf has been increased to hold the new sigset_t. On the alpha this has been prevented by using sc_reserved in sigcontext.		1999-09-29 15:06:27 +00:00
