Detailed Description

Signal handling.

Function Documentation

◆ signal_eventfd_close()

void signal_eventfd_close ( void )

Closes the eventfd and sets it to -1.

◆ signal_eventfd_get()

int signal_eventfd_get ( void )

Returns the signal eventfd.

Returns: the signal eventfd

◆ signal_eventfd_handler()

bool signal_eventfd_handler ( void )

Handles the signal_eventfd event.

Returns: false if the parent loop should exit, else true

◆ signal_eventfd_init()

bool signal_eventfd_init ( void )

Initializes the eventfd and installs a minimal signal handler for SIGTERM, SIGINT, and SIGHUP.

Returns: true on success, else false

◆ signal_handler()

void signal_handler ( int signo )

static

Minimal signal handler that writes to the eventfd to wake up the main loop.

Parameters

signo signal number

◆ signal_name()

const char * signal_name ( int signo )
