inet_addr

 

A useful support function named inet_addr converts a dotted IP address to a 32-bit unsigned long integer quantity. The inet_addr function is defined as

unsigned long inet_addr(
    const char FAR *cp 
); 

The cp field is a null-terminated character string that accepts an IP address in dotted notation. Note that this function returns an IP address as a 32-bit unsigned long integer in network-byte order.
