Member Function Documentation

struct in_addr ost::IPV4Cidr::getBroadcast ( void   )  const [read]

Compute the broadcast address associated with this cidr.

Returns:
system binary coded network address.

Get network address associated with this cidr.

Returns:
system binary coded address.

bool ost::IPV4Cidr::isMember ( const struct in_addr &  inaddr  )  const

See if a low level address object is a member of this cidr's net.

Parameters:
inaddr object to test.
Returns:
true if member of cidr.

bool ost::IPV4Cidr::isMember ( const struct sockaddr *  saddr  )  const

See if a socket address is a member of this cidr's network.

Parameters:
saddr pointer to test.
Returns:
true if member of cidr.
