SIGTERM, SIGSEGV, SIGINT, SIGILL, SIGABRT, SIGFPE (original) (raw)
| Defined in header | | | | ----------------------------------------------------------------------------- | | | | #define SIGTERM /*implementation defined*/ | | | | #define SIGSEGV /*implementation defined*/ | | | | #define SIGINT /*implementation defined*/ | | | | #define SIGILL /*implementation defined*/ | | | | #define SIGABRT /*implementation defined*/ | | | | #define SIGFPE /*implementation defined*/ | | |
Each of the above macro constants expands to an integer constant expression with distinct values, which represent different signals sent to the program.
| Constant | Explanation |
|---|---|
| SIGTERM | termination request, sent to the program |
| SIGSEGV | invalid memory access (segmentation fault) |
| SIGINT | external interrupt, usually initiated by the user |
| SIGILL | invalid program image, such as invalid instruction |
| SIGABRT | abnormal termination condition, as is e.g. initiated by std::abort() |
| SIGFPE | erroneous arithmetic operation such as divide by zero |
[edit] Notes
Additional signal names are specified by POSIX.
