Function Documentation

◆ ngcbTcpAccept()

int ngcbTcpAccept	(	int	fd,
		char *	erms )

Accept a tcp/ip client connection request and return the client socket.

◆ ngcbTcpClose()

int ngcbTcpClose ( int fd )

Close tcp/ip socket.

◆ ngcbTcpConnect()

int ngcbTcpConnect	(	const char *	service,
		char *	erms )

Connect to a tcp/ip socket service specified in the format "host:port". The function returns a client socket descriptor.

◆ ngcbTcpConnectTmo()

int ngcbTcpConnectTmo	(	const char *	service,
		int	tmo,
		char *	erms )

Cnnects to a tcp/ip socket service specified in the format "host:port". The function returns a client socket descriptor. The connect timeout is given in seconds. Zero or a negavitve number falls back to the default connection timeout as provided by the OS.

◆ ngcbTcpRead()

int ngcbTcpRead	(	int	fd,
		void *	buffer,
		size_t	size,
		char *	erms )

Read size bytes of from tcp/ip socket into buffer.

◆ ngcbTcpService()

int ngcbTcpService	(	const char *	service,
		char *	erms )

Open a tcp/ip server socket.

◆ ngcbTcpWrite()

int ngcbTcpWrite	(	int	fd,
		const void *	buffer,
		size_t	size,
		char *	erms )

Write size bytes of buffer to tcp/ip socket.
