This function converts a network address in ascii into the binary network address. The ascii representation can be CIDR-based (for example, 9.3.149.0/24) or class-based (for example, 9.3.149.0). The argument, af, specifies the family of the address. The argument, src, points the string being passed in. The argument, dst, points to a buffer where the function will store the resulting numeric address.

Return Values

If successful, 1 (one) is returned. If unseccessful, 0 (zero) is returned if the input is not a valid IPv4 string; or a -1 (negative one) with errno set to EAFNOSUPPORT if the af argument is unknown.
