2211 | /* We implement our own kill() using the undocumented system service |
2212 | sys$sigprc for one of two reasons: | |
2213 | ||
2214 | 1.) If the kill() in an older CRTL uses sys$forcex, causing the | |
f2610a60 CL |
2215 | target process to do a sys$exit, which usually can't be handled |
2216 | gracefully...certainly not by Perl and the %SIG{} mechanism. | |
2217 | ||
05c058bc CB |
2218 | 2.) If the kill() in the CRTL can't be called from a signal |
2219 | handler without disappearing into the ether, i.e., the signal | |
2220 | it purportedly sends is never trapped. Still true as of VMS 7.3. | |
2221 | ||
2222 | sys$sigprc has the same parameters as sys$forcex, but throws an exception | |
f2610a60 CL |
2223 | in the target process rather than calling sys$exit. |
2224 | ||
2225 | Note that distinguishing SIGSEGV from SIGBUS requires an extra arg | |
2226 | on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't | |
2227 | provide. On VMS 7.0+ this is taken care of by doing sys$sigprc | |
2228 | with condition codes C$_SIG0+nsig*8, catching the exception on the | |
2229 | target process and resignaling with appropriate arguments. | |
2230 | ||
2231 | But we don't have that VMS 7.0+ exception handler, so if you | |
2232 | Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well. | |
2233 | ||
2234 | Also note that SIGTERM is listed in the docs as being "unimplemented", | |
2235 | yet always seems to be signaled with a VMS condition code of 4 (and | |
2236 | correctly handled for that code). So we hardwire it in. | |
2237 | ||
2238 | Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal | |
2239 | number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather | |
2240 | than signalling with an unrecognized (and unhandled by CRTL) code. | |

5857 | ** All will take input specifications in either VMS or Unix syntax. On | |
5858 | ** failure, all return NULL. If successful, the routines listed below | |
748a9306 | 5859 | ** return a pointer to a buffer containing the appropriately |
a0d0e21e LW |
5860 | ** reformatted spec (and, therefore, subsequent calls to that routine |
5861 | ** will clobber the result), while the routines of the same names with | |
5862 | ** a _ts suffix appended will return a pointer to a mallocd string | |
5863 | ** containing the appropriately reformatted spec. | |
5864 | ** In all cases, only explicit syntax is altered; no check is made that | |
5865 | ** the resulting string is valid or that the directory in question | |
5866 | ** actually exists. | |
5867 | ** | |
5868 | ** fileify_dirspec() - convert a directory spec into the name of the | |
5869 | ** directory file (i.e. what you can stat() to see if it's a dir). | |
5870 | ** The style (VMS or Unix) of the result is the same as the style | |
5871 | ** of the parameter passed in. | |
5872 | ** pathify_dirspec() - convert a directory spec into a path (i.e. | |
5873 | ** what you prepend to a filename to indicate what directory it's in). | |
5874 | ** The style (VMS or Unix) of the result is the same as the style | |
5875 | ** of the parameter passed in. | |
5876 | ** tounixpath() - convert a directory spec into a Unix-style path. | |
5877 | ** tovmspath() - convert a directory spec into a VMS-style path. | |
5878 | ** tounixspec() - convert any file spec into a Unix-style file spec. | |
5879 | ** tovmsspec() - convert any file spec into a VMS-style spec. | |
360732b5 | 5880 | ** xxxxx_utf8() - Variants that support UTF8 encoding of Unix-Style file spec. |

10353 | * | |
10354 | * vms_do_aexec() and vms_do_exec() are called in response to the | |
10355 | * perl 'exec' function. If this follows a vfork call, then they | |
a6d05634 | 10356 | * call out the regular perl routines in doio.c which do an |
a0d0e21e LW |
10357 | * execvp (for those who really want to try this under VMS). |
10358 | * Otherwise, they do exactly what the perl docs say exec should | |
10359 | * do - terminate the current script and invoke a new command | |
10360 | * (See below for notes on command syntax.) | |
10361 | * | |
10362 | * do_aspawn() and do_spawn() implement the VMS side of the perl | |
10363 | * 'system' function. | |
10364 | * | |
10365 | * Note on command arguments to perl 'exec' and 'system': When handled | |
10366 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args | |
eed5d6a1 CB |
10367 | * are concatenated to form a DCL command string. If the first non-numeric |
10368 | * arg begins with '$' (i.e. the perl script had "\$ Type" or some such), | |
a6d05634 | 10369 | * the command string is handed off to DCL directly. Otherwise, |
a0d0e21e LW |
10370 | * the first token of the command is taken as the filespec of an image |
10371 | * to run. The filespec is expanded using a default type of '.EXE' and | |
3eeba6fb | 10372 | * the process defaults for device, directory, etc., and if found, the resultant |
a0d0e21e | 10373 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of |
3eeba6fb | 10374 | * the command string as parameters. This is perhaps a bit complicated, |
a0d0e21e LW |
10375 | * but I hope it will form a happy medium between what VMS folks expect |
10376 | * from lib$spawn and what Unix folks expect from exec. | |

12411 | * did not contain an explicit name or type, and the revision date is always | |
12412 | * updated at the end of the copy operation. If it is greater than 0, then | |
12413 | * it is interpreted as a bitmask, in which bit 0 indicates that timestamps | |

12415 | * that the revision date should be propagated. | |
12416 | * | |
