+ * Description:
+ * The inet_ntop() function converts a numeric address into a text string
+ * suitable for presentation.
+ *
+ * Input Parameters:
+ * af - The af argument specifies the family of the address. This can be
+ * AF_INET or AF_INET6.
+ * src - The src argument points to a buffer holding an address of the
+ * specified type. The address must be in network byte order.
+ * dst - The dst argument points to a buffer where the function stores
+ * the resulting text string; it shall not be NULL.
+ * size - The size argument specifies the size of this buffer, which must
+ * be large enough to hold the text string (INET_ADDRSTRLEN
+ * characters for IPv4, INET6_ADDRSTRLEN characters for IPv6).
+ *
+ * Returned Value:
+ * inet_ntop() returns a pointer to the buffer containing the text string
+ * if the conversion succeeds. Otherwise, NULL is returned and the errno
+ * is set to indicate the error. There follow errno values may be set:
+ *
+ * EAFNOSUPPORT - The af argument is invalid.

+ * Name: inet_pton
+ *
+ * Description:
+ * The inet_pton() function converts an address in its standard text
+ * presentation form into its numeric binary form.
+ *
+ * If the af argument of inet_pton() is AF_INET, the src string will be
+ * in the standard IPv4 dotted-decimal form:
+ *
+ * ddd.ddd.ddd.ddd
+ *
+ * where "ddd" is a one to three digit decimal number between 0 and 255.
+ *
+ * If the af argument of inet_pton() is AF_INET6, the src string will be in
+ * one of the following standard IPv6 text forms:
+ *
+ * 1. The preferred form is "x:x:x:x:x:x:x:x", where the 'x' s are the
+ * hexadecimal values of the eight 16-bit pieces of the address. Leading
+ * zeros in individual fields can be omitted, but there must be at least
+ * one numeral in every field.
+ *
+ * 2. A string of contiguous zero fields in the preferred form can be shown
+ * as "::". The "::" can only appear once in an address. Unspecified
+ * addresses ( "0:0:0:0:0:0:0:0" ) may be represented simply as "::".
+ *
+ * 3. A third form that is sometimes more convenient when dealing with a
+ * mixed environment of IPv4 and IPv6 nodes is "x:x:x:x:x:x:d.d.d.d",
+ * where the 'x' s are the hexadecimal values of the six high-order
+ * 16-bit pieces of the address, and the 'd' s are the decimal values
+ * of the four low-order 8-bit pieces of the address (standard IPv4
+ * representation).
+ *
+ * Input Parameters:
+ * af - The af argument specifies the family of the address. This can be
+ * AF_INET or AF_INET6.
+ * src - The src argument points to the string being passed in.
+ * dst - The dst argument points to a numstr into which the function stores
+ * the numeric address; this must be large enough to hold the numeric
+ * address (32 bits for AF_INET, 128 bits for AF_INET6).
+ *
+ * Returned Value:
+ * The inet_pton() function returns 1 if the conversion succeeds, with the
+ * address pointed to by dst in network byte order. It will return 0 if the
+ * input is not a valid IPv4 dotted-decimal string or a valid IPv6 address
+ * string, or -1 with errno set to EAFNOSUPPOR] if the af argument is unknown.
