intSIGABRT
-
This signal indicates an error detected by the program itself and reported by calling
abort. See section.
intSIGIOT
-
Generated by the PDP-11 "iot" instruction. On most machines,this is just another name for
SIGABRT.
intSIGTRAP
-
Generated by the machine's breakpoint instruction,and possibly other trap instructions. This signal is used by debuggers. Your program will probably only see
SIGTRAPif it is somehow executing bad instructions.
intSIGEMT
-
Emulator trap; this results from certain unimplemented instructions which might be emulated in software,or the operating system's failure to properly emulate them.
intSIGSYS
-
Bad system call; that is to say,the instruction to trap to the operating system was executed,but the code number for the system call to perform was invalid.
intSIGTERM
-
The
SIGTERMsignal is a generic signal used to cause program termination. UnlikeSIGKILL,this signal can be blocked,handled,and ignored. It is the normal way to politely ask a program to terminate. （编辑：济南站长网）
