Function Documentation

m0_net_hostname_to_ip()

M0_INTERNAL int m0_net_hostname_to_ip	(	const char *	hostname,
		char *	ip,
		enum m0_net_ip_format *	fmt
	)

This function convert the hostname/FQDN format to ip format. Here hostname can be FQDN or local machine hostname. Return value: = 0 in case of succesful fqdn to ip resolution. > 0 when gethostbyname fails (dns resolution failed). < 0 error.

Here is the caller graph for this function:

m0_net_ip_addr_eq()

M0_INTERNAL bool m0_net_ip_addr_eq	(	const struct m0_net_ip_addr *	addr1,
		const struct m0_net_ip_addr *	addr2,
		bool	is_ncmp
	)

This function is used to compare the fields in struct m0_net_ip_addr. If is_ncmp is true then numeric address fields are compared else string addr is compared. Returns true if addr1 and addr2 are equal else false.

m0_net_ip_parse()

M0_INTERNAL int m0_net_ip_parse	(	const char *	name,
		struct m0_net_ip_addr *	addr
	)

This function decodes addresses based on address format type such as lnet or inet address format. Example: lnet format: <ip><type>:<pid=12345>:<portal>:<tmid> for example:"192.168.96.128@tcp:12345:34:1" inet format: <family>:<type>:<ipaddr/hostname_FQDN><port> for example: "inet:tcp:127.0.0.1@3000" Return value: 0 in case of success. < 0 in case of error.
