Function Documentation

spdk_net_get_address_string()

int spdk_net_get_address_string	(	struct sockaddr *	sa,
		char *	addr,
		size_t	len
	)

Gets the address string for a given struct sockaddr.

Parameters

sa	sockaddr to get the address string for
addr	string to put the address
len	length of the the addr parameter

Returns

0 if successful, negative -errno otherwise

spdk_net_get_interface_name()

int spdk_net_get_interface_name	(	const char *	ip,
		char *	ifc,
		size_t	len
	)

Gets the name of the network interface for the given IP address.

Parameters

ip	IP address to find the interface name for
ifc	string output parameter for the interface name
len	length of the ifc parameter in bytes

Returns

0 if successful, the interface name will be copied to the ifc parameter -ENODEV if an interface name could not be identified -ENOMEM the provided ifc string was too small

spdk_net_is_loopback()

bool spdk_net_is_loopback

(

int

fd

)

Checks if the given fd is a loopback interface or not.

Parameters

fd	file descriptor to check

Returns

true if the fd is loopback, false if not
