I am missing the sigsetmask() function at link time when compiling
bash-1.05 under SCO Xenix 2.3 with development version 2.3.1b, and
alternately using gcc-1.37.1.
I have looked in the libraries here (ar t <libname>) and found no
mention of the function. I also grep'ed the sources and only found the
call - no function body.
Am I missing somethong from the sources? Is this a vendor supplied
library function? What is it supposed to do exactally?

(The real sigsetmask() returns the original mask, but there's no good way to emulate this that I know of, that won't cause problems.) The following is a rough, UNTESTED (i.e. use at your own risk) quick approximation to sigsetmask(). I should note that you probably configured bash wrong; I didn't see any calls to sigsetmask() outside the job-control code, which won't work under SCO Xenix or SCO Unix (which has job control, but it's of the POSIX variety so bash won't work.) I might have missed something, though. int sigsetmask(mask) int mask; { int sig; for (sig = 1; sig < NSIG; sig++) { if ((mask >>= 1) & 1) sighold(sig); else sigrelse(sig); } return 0; /* should return the old mask */ } ++Brandon -- Me: Brandon S.
