3 * VMS-specific routines for perl5
6 * August 2005 Convert VMS status code to UNIX status codes
7 * August 2000 tweaks to vms_image_init, my_flush, my_fwrite, cando_by_name,
8 * and Perl_cando by Craig Berry
9 * 29-Aug-2000 Charles Lane's piping improvements rolled in
10 * 20-Aug-1999 revisions by Charles Bailey bailey@newman.upenn.edu

51 /* Set the maximum filespec size here as it is larger for EFS file
53 * Not fully implemented at this time because the larger size
54 * will likely impact the stack local storage requirements of
55 * threaded code, and probably cause hard to diagnose failures.
56 * To implement the larger sizes, all places where filename
57 * storage is put on the stack need to be changed to use
58 * New()/SafeFree() instead.

1630 sys$sigprc for one of two reasons:
1632 1.) If the kill() in an older CRTL uses sys$forcex, causing the
1633 target process to do a sys$exit, which usually can't be handled
1634 gracefully...certainly not by Perl and the %SIG{} mechanism.
1636 2.) If the kill() in the CRTL can't be called from a signal
1637 handler without disappearing into the ether, i.e., the signal
1638 it purportedly sends is never trapped. Still true as of VMS 7.3.
1640 sys$sigprc has the same parameters as sys$forcex, but throws an exception
1641 in the target process rather than calling sys$exit.
1643 Note that distinguishing SIGSEGV from SIGBUS requires an extra arg
1644 on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't
1645 provide. On VMS 7.0+ this is taken care of by doing sys$sigprc
1646 with condition codes C$_SIG0+nsig*8, catching the exception on the
1647 target process and resignaling with appropriate arguments.
1649 But we don't have that VMS 7.0+ exception handler, so if you
1650 Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well.
1652 Also note that SIGTERM is listed in the docs as being "unimplemented",
1653 yet always seems to be signaled with a VMS condition code of 4 (and
1654 correctly handled for that code). So we hardwire it in.
1656 Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal
1657 number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather
1658 than signalling with an unrecognized (and unhandled by CRTL) code.

4390 ** of the parameter passed in.

4393 ** The style (VMS or Unix) of the result is the same as the style
4394 ** of the parameter passed in.
