1183 sys$sigprc for one of two reasons:
1185 1.) If the kill() in an older CRTL uses sys$forcex, causing the
1186 target process to do a sys$exit, which usually can't be handled
1187 gracefully...certainly not by Perl and the %SIG{} mechanism.
1189 2.) If the kill() in the CRTL can't be called from a signal
1190 handler without disappearing into the ether, i.e., the signal
1191 it purportedly sends is never trapped. Still true as of VMS 7.3.
1193 sys$sigprc has the same parameters as sys$forcex, but throws an exception
1194 in the target process rather than calling sys$exit.
1196 Note that distinguishing SIGSEGV from SIGBUS requires an extra arg
1197 on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't
1198 provide. On VMS 7.0+ this is taken care of by doing sys$sigprc
1199 with condition codes C$_SIG0+nsig*8, catching the exception on the
1200 target process and resignaling with appropriate arguments.
1202 But we don't have that VMS 7.0+ exception handler, so if you
1203 Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well.
1205 Also note that SIGTERM is listed in the docs as being "unimplemented",
1206 yet always seems to be signaled with a VMS condition code of 4 (and
1207 correctly handled for that code). So we hardwire it in.
1209 Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal
1210 number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather
1211 than signalling with an unrecognized (and unhandled by CRTL) code.

3962 * command execution '&'. All of these capabilities are provided to any
3963 * C program which calls this procedure as the first thing in the
3965 * The piping mechanism will probably work with almost any 'filter' type
3966 * of program. With suitable modification, it may useful for other
