Function patch_seq_signal_ignore 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn patch_seq_signal_ignore(
    stack: Stack,
) -> Stack

Ignore a signal entirely

Stack effect: ( signal-num – )

The signal will be ignored - it won’t terminate the process or set any flag. Useful for SIGPIPE in network servers.

Safety

Stack must have an Int (signal number) on top
