.SS "#define for_each_context_in_cq(l)   for (l = libnet_cq_head(); libnet_cq_last(); l = libnet_cq_next())"
.PP
Provides an interface to iterate through the context queue of libnet contexts. Before calling this macro, be sure to set the queue using \fBlibnet_cq_head()\fP.

IPv6 error code 
.SS "#define LIBNET_DONT_RESOLVE   0"
.PP
Used for libnet's name resolution functions, specifies that no DNS lookups should be performed and the IP address should be kept in numeric form. 
.SS "#define LIBNET_ERRBUF_SIZE   0x100"
.PP
The libnet error buffer is 256 bytes long. 
.SS "#define LIBNET_MAX_PACKET   0xffff"
.PP
The biggest an IP packet can be -- 65,535 bytes. 
.SS "#define LIBNET_MAXOPTION_SIZE   0x28"
.PP
IP and TCP options can be up to 40 bytes long. 
.SS "#define LIBNET_OFF   1"
.PP
Used several places, to specify 'on' or 'one' 
.SS "#define LIBNET_ON   0"
.PP
Used several places, to specify 'on' or 'one' 
.SS "#define LIBNET_PR2   0"
.PP
Used for \fBlibnet_get_prand()\fP to specify function disposition 
.SS "#define LIBNET_RESOLVE   1"
.PP
Used for libnet's name resolution functions, specifies that a DNS lookup can be performed if needed to resolve the IP address to a canonical form.
