Function Documentation

int getListenerSocket	(	int *	sd,
		char *	hostname,
		unsigned short	port,
		struct sockaddr_in *	servAddr
	)

Establish listener socket.

Parameters:

	sd	socket descriptor to assign
	hostname	XPortSim server hostname
	port	XPortSim server TCP/IP port
	servAddr	socket address

void* gpioListener

(

)

GPIO handler.

Receives incoming XPort GPIO traffic and returns appropriate messages.

int main	(	int	argc,
		char *	argv[]
	)

XPortSim Entry Point.

Starts XPortSim server.

Parameters:

	argc	number of command line arguments
	argv	command line parameters

Returns:

0 if normal termination, error code otherwise

int sendBytes	(	int	sd,
		char *	buf,
		int	len
	)

send bytes to specified socket.

Parameters:

	sd	socket descriptor
	buf	byte buffer
	len	number of bytes to send

int sendMessage	(	int	sd,
		char *	msg
	)

Send bytes to specified socket.

Parameters:

	sd	socket descriptor
	msg	bytes to send.

int sendResponse	(	int	sd,
		XPortResponse *	xpResponse
	)

Send XPortResponse to specified socket.

Parameters:

	sd	socket descriptor
	xpResponse	pointer to XPortResponse

void* serialListener

(

)

Serial handler.

Receives incoming XPort Serial traffic and returns appropriate messages. ToDo: use local serial port for full emulation.

void sig_handler

(

int

sig

)

Signal handler (SIGINT, SIGTERM) for XPortSim process.

Parameters:

sig

signal received

void startMockXPort

(

const char *

host

)

start XPortSim server

Parameters:

host

hostname

void startMockXPort

(

char *

host

)

Start XPortSim server.

Parameters:

host

hostname
