2376 | /* We implement our own kill() using the undocumented system service |
2377 | sys$sigprc for one of two reasons: | |
2378 | ||
2379 | 1.) If the kill() in an older CRTL uses sys$forcex, causing the | |
f2610a60 CL |
2380 | target process to do a sys$exit, which usually can't be handled |
2381 | gracefully...certainly not by Perl and the %SIG{} mechanism. | |
2382 | ||
05c058bc CB |
2383 | 2.) If the kill() in the CRTL can't be called from a signal |
2384 | handler without disappearing into the ether, i.e., the signal | |
2385 | it purportedly sends is never trapped. Still true as of VMS 7.3. | |
2386 | ||
2387 | sys$sigprc has the same parameters as sys$forcex, but throws an exception | |
f2610a60 CL |
2388 | in the target process rather than calling sys$exit. |
2389 | ||
2390 | Note that distinguishing SIGSEGV from SIGBUS requires an extra arg | |
2391 | on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't | |
2392 | provide. On VMS 7.0+ this is taken care of by doing sys$sigprc | |
2393 | with condition codes C$_SIG0+nsig*8, catching the exception on the | |
2394 | target process and resignaling with appropriate arguments. | |
2395 | ||
2396 | But we don't have that VMS 7.0+ exception handler, so if you | |
2397 | Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well. | |
2398 | ||
2399 | Also note that SIGTERM is listed in the docs as being "unimplemented", | |
2400 | yet always seems to be signaled with a VMS condition code of 4 (and | |
2401 | correctly handled for that code). So we hardwire it in. | |
2402 | ||
2403 | Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal | |
2404 | number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather | |
2405 | than signalling with an unrecognized (and unhandled by CRTL) code. | |

a0d0e21e LW |
10602 | * execvp (for those who really want to try this under VMS). |
10603 | * Otherwise, they do exactly what the perl docs say exec should | |

10610 | * Note on command arguments to perl 'exec' and 'system': When handled | |
10611 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args | |
eed5d6a1 CB |
10612 | * are concatenated to form a DCL command string. If the first non-numeric |
10613 | * arg begins with '$' (i.e. the perl script had "\$ Type" or some such), | |
a6d05634 | 10614 | * the command string is handed off to DCL directly. Otherwise, |
a0d0e21e LW |
10615 | * the first token of the command is taken as the filespec of an image |
10616 | * to run. The filespec is expanded using a default type of '.EXE' and | |
3eeba6fb | 10617 | * the process defaults for device, directory, etc., and if found, the resultant |
a0d0e21e | 10618 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of |
3eeba6fb | 10619 | * the command string as parameters. This is perhaps a bit complicated, |
a0d0e21e LW |
10620 | * but I hope it will form a happy medium between what VMS folks expect |
10621 | * from lib$spawn and what Unix folks expect from exec. | |
