Struct sigaction 

#[repr(C)]
pub struct sigaction {
    pub sa_handler: Option<extern "C" fn(c_int)>,
    pub sa_flags: c_int,
    pub sa_restorer: Option<unsafe extern "C" fn()>,
    pub sa_mask: sigset_t,
}

cbindgen:ignore See https://pubs.opengroup.org/onlinepubs/9799919799/basedefs/signal.h.html.

Implementation

This struct in Rust is missing the sa_sigaction field. The stucture in cbindgen uses a union to combine sa_handler and sa_sigaction. POSIX states that both fields shall not be used simultaneously.

Fields

sa_handler: Option<extern "C" fn(c_int)>

Pointer to a signal-catching function or one of the SIG_IGN or SIG_DFL.

sa_flags: c_int

Special flags.

sa_restorer: Option<unsafe extern "C" fn()>

Non-POSIX, see https://www.man7.org/linux/man-pages/man2/sigaction.2.html.

Not intended for application use. A sigaction wrapper function is intended to use this to store the location of the trampoline code and setting the SA_RESTORER flag in sa_flags.

sa_mask: sigset_t

Set of signals to be blocked during execution of the signal handling function.
