Expand description

An enum representing signals on UNIX-like systems.

On non-unix systems, this enum is mostly useless and is only there to keep coherency between the different OSes.

If you want the list of the supported signals on the current system, use SystemExt::SUPPORTED_SIGNALS.

Variants§

§

Hangup

Hangup detected on controlling terminal or death of controlling process.

§

Interrupt

Interrupt from keyboard.

§

Quit

Quit from keyboard.

§

Illegal

Illegal instruction.

§

Trap

Trace/breakpoint trap.

§

Abort

Abort signal from C abort function.

§

IOT

IOT trap. A synonym for SIGABRT.

§

Bus

Bus error (bad memory access).

§

FloatingPointException

Floating point exception.

§

Kill

Kill signal.

§

User1

User-defined signal 1.

§

Segv

Invalid memory reference.

§

User2

User-defined signal 2.

§

Pipe

Timer signal from C alarm function.

§

Term

Termination signal.

§

Child stopped or terminated.

§

Continue

Continue if stopped.

§

Stop

Stop process.

§

TSTP

Stop typed at terminal.

§

§

IO

I/O now possible.

§

Poll

Pollable event (Sys V). Synonym for IO

§

Power

Power failure (System V).

Doesn’t exist on apple systems so will be ignored.

§

Sys

Bad argument to routine (SVr4).
