1075 | sys$sigprc for one of two reasons: | |
1076 | ||
1077 | 1.) If the kill() in an older CRTL uses sys$forcex, causing the | |
f2610a60 CL |
1078 | target process to do a sys$exit, which usually can't be handled |
1079 | gracefully...certainly not by Perl and the %SIG{} mechanism. | |
1080 | ||
05c058bc CB |
1081 | 2.) If the kill() in the CRTL can't be called from a signal |
1082 | handler without disappearing into the ether, i.e., the signal | |
1083 | it purportedly sends is never trapped. Still true as of VMS 7.3. | |
1084 | ||
1085 | sys$sigprc has the same parameters as sys$forcex, but throws an exception | |
f2610a60 CL |
1086 | in the target process rather than calling sys$exit. |
1087 | ||
1088 | Note that distinguishing SIGSEGV from SIGBUS requires an extra arg | |
1089 | on the ACCVIO condition, which sys$sigprc (and sys$forcex) don't | |
1090 | provide. On VMS 7.0+ this is taken care of by doing sys$sigprc | |
1091 | with condition codes C$_SIG0+nsig*8, catching the exception on the | |
1092 | target process and resignaling with appropriate arguments. | |
1093 | ||
1094 | But we don't have that VMS 7.0+ exception handler, so if you | |
1095 | Perl_my_kill(.., SIGSEGV) it will show up as a SIGBUS. Oh well. | |
1096 | ||
1097 | Also note that SIGTERM is listed in the docs as being "unimplemented", | |
1098 | yet always seems to be signaled with a VMS condition code of 4 (and | |
1099 | correctly handled for that code). So we hardwire it in. | |
1100 | ||
1101 | Unlike the VMS 7.0+ CRTL kill() function, we actually check the signal | |
1102 | number to see if it's valid. So Perl_my_kill(pid,0) returns -1 rather | |
1103 | than signalling with an unrecognized (and unhandled by CRTL) code. | |
