2293 | 2.) If the kill() in the CRTL can't be called from a signal |
2294 | handler without disappearing into the ether, i.e., the signal | |
2295 | it purportedly sends is never trapped. Still true as of VMS 7.3. | |
2296 | ||
2297 | sys$sigprc has the same parameters as sys$forcex, but throws an exception | |
f2610a60 CL |
2298 | in the target process rather than calling sys$exit. |
2299 | ||
2300 | Note that distinguishing SIGSEGV from SIGBUS requires an extra arg | |
2301 | on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't | |
2302 | provide. On VMS 7.0+ this is taken care of by doing sys$sigprc | |
2303 | with condition codes C$_SIG0+nsig*8, catching the exception on the | |
2304 | target process and resignaling with appropriate arguments. | |
2305 | ||
2306 | But we don't have that VMS 7.0+ exception handler, so if you | |
2307 | Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well. | |
2308 | ||
2309 | Also note that SIGTERM is listed in the docs as being "unimplemented", | |
2310 | yet always seems to be signaled with a VMS condition code of 4 (and | |
2311 | correctly handled for that code). So we hardwire it in. | |
2312 | ||
2313 | Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal | |
2314 | number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather | |
2315 | than signalling with an unrecognized (and unhandled by CRTL) code. | |

748a9306 | 5967 | ** return a pointer to a buffer containing the appropriately |
a0d0e21e LW |

5970 | ** a _ts suffix appended will return a pointer to a mallocd string | |
5971 | ** containing the appropriately reformatted spec. | |
5972 | ** In all cases, only explicit syntax is altered; no check is made that | |
5973 | ** the resulting string is valid or that the directory in question | |

5976 | ** fileify_dirspec() - convert a directory spec into the name of the | |

5978 | ** The style (VMS or Unix) of the result is the same as the style | |
5979 | ** of the parameter passed in. | |
5980 | ** pathify_dirspec() - convert a directory spec into a path (i.e. | |
5981 | ** what you prepend to a filename to indicate what directory it's in). | |
5982 | ** The style (VMS or Unix) of the result is the same as the style | |
5983 | ** of the parameter passed in. | |
5984 | ** tounixpath() - convert a directory spec into a Unix-style path. | |
5985 | ** tovmspath() - convert a directory spec into a VMS-style path. | |
5986 | ** tounixspec() - convert any file spec into a Unix-style file spec. | |
5987 | ** tovmsspec() - convert any file spec into a VMS-style spec. | |

a6d05634 | 10504 | * call out the regular perl routines in doio.c which do an |
a0d0e21e LW |
10505 | * execvp (for those who really want to try this under VMS). |
10506 | * Otherwise, they do exactly what the perl docs say exec should | |
10507 | * do - terminate the current script and invoke a new command | |
10508 | * (See below for notes on command syntax.) | |
10509 | * | |
10510 | * do_aspawn() and do_spawn() implement the VMS side of the perl | |

10512 | * | |
10513 | * Note on command arguments to perl 'exec' and 'system': When handled | |
10514 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args | |
eed5d6a1 CB |
10515 | * are concatenated to form a DCL command string. If the first non-numeric |
10516 | * arg begins with '$' (i.e. the perl script had "\$ Type" or some such), | |
a6d05634 | 10517 | * the command string is handed off to DCL directly. Otherwise, |
a0d0e21e LW |
10518 | * the first token of the command is taken as the filespec of an image |
10519 | * to run. The filespec is expanded using a default type of '.EXE' and | |
3eeba6fb | 10520 | * the process defaults for device, directory, etc., and if found, the resultant |
a0d0e21e | 10521 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of |
3eeba6fb | 10522 | * the command string as parameters. This is perhaps a bit complicated, |
a0d0e21e LW |
10523 | * but I hope it will form a happy medium between what VMS folks expect |
10524 | * from lib$spawn and what Unix folks expect from exec. | |

11288 | * | |

11301 | * If the specified user does not exist, getpwuid and getpwnam return NULL. | |
11302 | * | |
11303 | * pw_uid is the full UIC (eg. what's returned by stat() in st_uid). | |
11304 | * not the UIC member number (eg. what's returned by getuid()), | |
11305 | * getpwuid() can accept either as input (if uid is specified, the caller's | |
11306 | * UIC group is used), though it won't recognise gid=0. | |

11308 | * Note that in VMS it is necessary to have GRPPRV or SYSPRV to return | |

12930 | * propagated to the output file at creation iff the output file specification | |
12931 | * did not contain an explicit name or type, and the revision date is always | |
12932 | * updated at the end of the copy operation. If it is greater than 0, then | |
12933 | * it is interpreted as a bitmask, in which bit 0 indicates that timestamps | |

12935 | * that the revision date should be propagated. | |
12936 | * | |
