1631 | /* We implement our own kill() using the undocumented system service |
1632 | sys$sigprc for one of two reasons: | |
1633 | ||
1634 | 1.) If the kill() in an older CRTL uses sys$forcex, causing the | |
f2610a60 CL |
1635 | target process to do a sys$exit, which usually can't be handled |
1636 | gracefully...certainly not by Perl and the %SIG{} mechanism. | |
1637 | ||
05c058bc CB |
1638 | 2.) If the kill() in the CRTL can't be called from a signal |
1639 | handler without disappearing into the ether, i.e., the signal | |
1640 | it purportedly sends is never trapped. Still true as of VMS 7.3. | |
1641 | ||
1642 | sys$sigprc has the same parameters as sys$forcex, but throws an exception | |
f2610a60 CL |
1643 | in the target process rather than calling sys$exit. |
1644 | ||
1645 | Note that distinguishing SIGSEGV from SIGBUS requires an extra arg | |
1646 | on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't | |
1647 | provide. On VMS 7.0+ this is taken care of by doing sys$sigprc | |
1648 | with condition codes C$_SIG0+nsig*8, catching the exception on the | |
1649 | target process and resignaling with appropriate arguments. | |
1650 | ||
1651 | But we don't have that VMS 7.0+ exception handler, so if you | |
1652 | Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well. | |
1653 | ||
1654 | Also note that SIGTERM is listed in the docs as being "unimplemented", | |
1655 | yet always seems to be signaled with a VMS condition code of 4 (and | |
1656 | correctly handled for that code). So we hardwire it in. | |
1657 | ||
1658 | Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal | |
1659 | number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather | |
1660 | than signalling with an unrecognized (and unhandled by CRTL) code. | |
