1099 sys$sigprc for one of two reasons:
1101 1.) If the kill() in an older CRTL uses sys$forcex, causing the
1102 target process to do a sys$exit, which usually can't be handled
1103 gracefully...certainly not by Perl and the %SIG{} mechanism.
1105 2.) If the kill() in the CRTL can't be called from a signal
1106 handler without disappearing into the ether, i.e., the signal
1107 it purportedly sends is never trapped. Still true as of VMS 7.3.
1109 sys$sigprc has the same parameters as sys$forcex, but throws an exception
1110 in the target process rather than calling sys$exit.
1112 Note that distinguishing SIGSEGV from SIGBUS requires an extra arg
1113 on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't
1114 provide. On VMS 7.0+ this is taken care of by doing sys$sigprc
1115 with condition codes C$_SIG0+nsig*8, catching the exception on the
1116 target process and resignaling with appropriate arguments.
1118 But we don't have that VMS 7.0+ exception handler, so if you
1119 Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well.
1121 Also note that SIGTERM is listed in the docs as being "unimplemented",
1122 yet always seems to be signaled with a VMS condition code of 4 (and
1123 correctly handled for that code). So we hardwire it in.
1125 Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal
1126 number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather
1127 than signalling with an unrecognized (and unhandled by CRTL) code.

3859 * getredirection() is intended to aid in porting C programs

3861 * '>' and '<' I/O redirection, or command line wild card expansion,
3862 * or a command line pipe mechanism using the '|' AND background
3863 * command execution '&'. All of these capabilities are provided to any
3864 * C program which calls this procedure as the first thing in the
3866 * The piping mechanism will probably work with almost any 'filter' type
3867 * of program. With suitable modification, it may useful for other
3868 * portability problems as well.
