1394 | sys$sigprc for one of two reasons: | |
1395 | ||
1396 | 1.) If the kill() in an older CRTL uses sys$forcex, causing the | |
f2610a60 CL |
1397 | target process to do a sys$exit, which usually can't be handled |
1398 | gracefully...certainly not by Perl and the %SIG{} mechanism. | |
1399 | ||
05c058bc CB |
1400 | 2.) If the kill() in the CRTL can't be called from a signal |
1401 | handler without disappearing into the ether, i.e., the signal | |
1402 | it purportedly sends is never trapped. Still true as of VMS 7.3. | |
1403 | ||
1404 | sys$sigprc has the same parameters as sys$forcex, but throws an exception | |
f2610a60 CL |
1405 | in the target process rather than calling sys$exit. |
1406 | ||
1407 | Note that distinguishing SIGSEGV from SIGBUS requires an extra arg | |
1408 | on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't | |
1409 | provide. On VMS 7.0+ this is taken care of by doing sys$sigprc | |
1410 | with condition codes C$_SIG0+nsig*8, catching the exception on the | |
1411 | target process and resignaling with appropriate arguments. | |
1412 | ||
1413 | But we don't have that VMS 7.0+ exception handler, so if you | |
1414 | Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well. | |
1415 | ||
1416 | Also note that SIGTERM is listed in the docs as being "unimplemented", | |
1417 | yet always seems to be signaled with a VMS condition code of 4 (and | |
1418 | correctly handled for that code). So we hardwire it in. | |
1419 | ||
1420 | Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal | |
1421 | number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather | |
1422 | than signalling with an unrecognized (and unhandled by CRTL) code. | |

3440 | ** The following routines are provided to make life easier when | |
3441 | ** converting among VMS-style and Unix-style directory specifications. | |
3442 | ** All will take input specifications in either VMS or Unix syntax. On | |
3443 | ** failure, all return NULL. If successful, the routines listed below | |
748a9306 | 3444 | ** return a pointer to a buffer containing the appropriately |
a0d0e21e LW |
3445 | ** reformatted spec (and, therefore, subsequent calls to that routine |
3446 | ** will clobber the result), while the routines of the same names with | |
3447 | ** a _ts suffix appended will return a pointer to a mallocd string | |
3448 | ** containing the appropriately reformatted spec. | |
3449 | ** In all cases, only explicit syntax is altered; no check is made that | |
3450 | ** the resulting string is valid or that the directory in question | |
3451 | ** actually exists. | |
3452 | ** | |
3453 | ** fileify_dirspec() - convert a directory spec into the name of the | |
3454 | ** directory file (i.e. what you can stat() to see if it's a dir). | |
3455 | ** The style (VMS or Unix) of the result is the same as the style | |
3456 | ** of the parameter passed in. | |
3457 | ** pathify_dirspec() - convert a directory spec into a path (i.e. | |
3458 | ** what you prepend to a filename to indicate what directory it's in). | |
3459 | ** The style (VMS or Unix) of the result is the same as the style | |
3460 | ** of the parameter passed in. | |
3461 | ** tounixpath() - convert a directory spec into a Unix-style path. | |
3462 | ** tovmspath() - convert a directory spec into a VMS-style path. | |
3463 | ** tounixspec() - convert any file spec into a Unix-style file spec. | |
3464 | ** tovmsspec() - convert any file spec into a VMS-style spec. | |
