:Hi all,
:
:What is the proper way for obtaining the signal mask from
:within the jmp_buf struct on 4.x or -current? Previously
:with the JDK port for < 3.x we did something like this:
:
: signalMask = jmpbuf[0]._sjb[6];
:
:This no longer works now that we support >32 signals. Is
:there a better, more portable way that will work for all
:versions of FreeBSD?
:
:Thanks.

The only portable way I can think of is to create
super-jump-buf structure --- one containing the
standard jmpbuf plus a signal mask, and then make
an extra system call to populate the signal mask
portion of the structure.
