uint32 nmi_inet_addr ( char *  pcIpAddr)
Parameters
[in]pcIpAddrA null terminated string containing the IP address in IPv4 dotted-decimal address.
Returns
Unsigned 32-bit integer representing the IP address in Network byte order (eg. "192.168.10.1" will be expressed as 0x010AA8C0).
         Synchronous function which returns a BSD socket compliant Internet Protocol (IPv4) socket address.
         This IPv4 address in the input string parameter could either be specified as a hostname, or as a numeric string
         representation like n.n.n.n known as the IPv4 dotted-decimal format (i.e. "192.168.10.1").
         This function is used whenever an ip address needs to be set in the proper format
         (i.e. for the @ref tstrM2MIPConfig structure).
Parameters
[in]pcIpAddrA null terminated string containing the IP address in IPv4 dotted-decimal address.
Returns
Unsigned 32-bit integer representing the IP address in Network byte order (eg. "192.168.10.1" will be expressed as 0x010AA8C0).
