2275 | Note that distinguishing SIGSEGV from SIGBUS requires an extra arg | |
2276 | on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't | |
2277 | provide. On VMS 7.0+ this is taken care of by doing sys$sigprc | |
2278 | with condition codes C$_SIG0+nsig*8, catching the exception on the | |
2279 | target process and resignaling with appropriate arguments. | |
2280 | ||
2281 | But we don't have that VMS 7.0+ exception handler, so if you | |
2282 | Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well. | |
2283 | ||
2284 | Also note that SIGTERM is listed in the docs as being "unimplemented", | |
2285 | yet always seems to be signaled with a VMS condition code of 4 (and | |
2286 | correctly handled for that code). So we hardwire it in. | |
2287 | ||
2288 | Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal | |
2289 | number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather | |
2290 | than signalling with an unrecognized (and unhandled by CRTL) code. | |

5885 | ** a _ts suffix appended will return a pointer to a mallocd string | |
5886 | ** containing the appropriately reformatted spec. | |
5887 | ** In all cases, only explicit syntax is altered; no check is made that | |
5888 | ** the resulting string is valid or that the directory in question | |

5891 | ** fileify_dirspec() - convert a directory spec into the name of the | |

5893 | ** The style (VMS or Unix) of the result is the same as the style | |
5894 | ** of the parameter passed in. | |
5895 | ** pathify_dirspec() - convert a directory spec into a path (i.e. | |
5896 | ** what you prepend to a filename to indicate what directory it's in). | |
5897 | ** The style (VMS or Unix) of the result is the same as the style | |
5898 | ** of the parameter passed in. | |
5899 | ** tounixpath() - convert a directory spec into a Unix-style path. | |
5900 | ** tovmspath() - convert a directory spec into a VMS-style path. | |
5901 | ** tounixspec() - convert any file spec into a Unix-style file spec. | |
5902 | ** tovmsspec() - convert any file spec into a VMS-style spec. | |

8927 | * getredirection() is intended to aid in porting C programs | |
8928 | * to VMS (Vax-11 C). The native VMS environment does not support | |
8929 | * '>' and '<' I/O redirection, or command line wild card expansion, | |
8930 | * or a command line pipe mechanism using the '|' AND background | |
8931 | * command execution '&'. All of these capabilities are provided to any | |
8932 | * C program which calls this procedure as the first thing in the | |
8933 | * main program. | |
8934 | * The piping mechanism will probably work with almost any 'filter' type | |
8935 | * of program. With suitable modification, it may useful for other | |
8936 | * portability problems as well. | |

10308 | * the current script is trying a Unix-style fork/exec. | |
10309 | * | |
10310 | * vms_do_aexec() and vms_do_exec() are called in response to the | |
10311 | * perl 'exec' function. If this follows a vfork call, then they | |
a6d05634 | 10312 | * call out the regular perl routines in doio.c which do an |
a0d0e21e LW |
10313 | * execvp (for those who really want to try this under VMS). |
10314 | * Otherwise, they do exactly what the perl docs say exec should | |
10315 | * do - terminate the current script and invoke a new command | |
10316 | * (See below for notes on command syntax.) | |
10317 | * | |
10318 | * do_aspawn() and do_spawn() implement the VMS side of the perl | |
10319 | * 'system' function. | |
10320 | * | |
10321 | * Note on command arguments to perl 'exec' and 'system': When handled | |
10322 | * in 'VMSish fashion' (i.e. not after a call to vfork) The args | |
eed5d6a1 CB |
10323 | * are concatenated to form a DCL command string. If the first non-numeric |
10324 | * arg begins with '$' (i.e. the perl script had "\$ Type" or some such), | |
a6d05634 | 10325 | * the command string is handed off to DCL directly. Otherwise, |
a0d0e21e LW |
10326 | * the first token of the command is taken as the filespec of an image |
10327 | * to run. The filespec is expanded using a default type of '.EXE' and | |
3eeba6fb | 10328 | * the process defaults for device, directory, etc., and if found, the resultant |
a0d0e21e | 10329 | * filespec is invoked using the DCL verb 'MCR', and passed the rest of |
3eeba6fb | 10330 | * the command string as parameters. This is perhaps a bit complicated, |
a0d0e21e LW |
10331 | * but I hope it will form a happy medium between what VMS folks expect |
10332 | * from lib$spawn and what Unix folks expect from exec. | |

11169 | * If the specified user does not exist, getpwuid and getpwnam return NULL. | |
11170 | * | |
11171 | * pw_uid is the full UIC (eg. what's returned by stat() in st_uid). | |
11172 | * not the UIC member number (eg. what's returned by getuid()), | |
11173 | * getpwuid() can accept either as input (if uid is specified, the caller's | |
11174 | * UIC group is used), though it won't recognise gid=0. | |
11175 | * | |
11176 | * Note that in VMS it is necessary to have GRPPRV or SYSPRV to return | |
11177 | * information about other users in your group or in other groups, respectively. | |
11178 | * If the required privilege is not available, then these routines fill only | |

12344 | * | |
12345 | * Copies contents and attributes of spec_in to spec_out, except owner | |
12346 | * and protection information. Name and type of spec_in are used as | |
a3e9d8c9 | 12347 | * defaults for spec_out. The third parameter specifies whether rmscopy() |
12348 | * should try to propagate timestamps from the input file to the output file. | |
12349 | * If it is less than 0, no timestamps are preserved. If it is 0, then | |
12350 | * rmscopy() will behave similarly to the DCL COPY command: timestamps are | |
12351 | * propagated to the output file at creation iff the output file specification | |
12352 | * did not contain an explicit name or type, and the revision date is always | |
12353 | * updated at the end of the copy operation. If it is greater than 0, then | |
12354 | * it is interpreted as a bitmask, in which bit 0 indicates that timestamps | |
12355 | * other than the revision date should be propagated, and bit 1 indicates | |
12356 | * that the revision date should be propagated. | |
12357 | * | |
12358 | * Returns 1 on success; returns 0 and sets errno and vaxc$errno on failure. | |
