7.1. IPADDR

The IPADDR structure is used to specify a local IP address. The data structure definition is as follows:

    typedef struct
    {
        unsigned char     ip_ver;
        union{
                unsigned int     ipv4;
                unsigned int     ipv6[4]
             }u_ipaddr;
    }IPADDR, *PIPADDR; 

Table 38 describes the meaning of each field in the IPCCLIB_START_DATA data structure.

Table 38. IPADDR Field Descriptions
