Public Attributes

Return	Name	Description
my_socket	fd	The real socket descriptor.
char	is_unix_domain_socket	Is this a Unix-domain socket?
char	is_extra_port	Is this a socket opened for the extra port?
unsigned short	address_family	Address family of the socket. (See sa_family from struct sockaddr).
struct PSI_socket *	m_psi	The instrumentation hook. Note that this hook is not conditionally defined, for binary compatibility of the MYSQL_SOCKET interface.
