signal on ia32
ANSI C signal handling
sys_signal(int sig, __sighandler_t handler)| number | 48 (0x30) |
|---|---|
| abi | i386 |
| entry point | sys_signal |
| since | Linux 3.3 or earlier (3.3 is the first release scanned for ia32) |
| man page | signal(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
eax | 48, the syscall number |
ebx | int sig |
ecx | __sighandler_t handler |
eax | the return value |
Then run int 0x80 to enter the kernel.
This compat ABI is only available when the kernel is built with CONFIG_IA32_EMULATION.
