Now I finally understand why trying to use the following
construct to get the signalmask no longer works with
version >= 4.0.
int signalmask = my_sigjmp_buf._sjb[6];
The status control word is there now and the signalmask
comes after because its size can vary. In theory at least
I should be able to get the signalmask now with something
along the following lines.
memcpy(signalmask, &(my_sigjmp_buf._sjb[7]),
sizeof(sigset_t));
Thanks.
