[lwip-devel] [patch #7130] mib2.c: remove meaningless const qualifiers

[Bill Auerbach]

Follow-up Comment #12, patch #7130 (project lwip):

Here's what I agree to: :-)

If snmp_nodes will not be changed at any time:

struct mib_node const * const snmp_nodes[28] = { (const struct
mib_node*)&snmp_scalar, ...

If snmp_nodes will be changed then:

struct mib_node const * snmp_nodes[28] = { (const struct
mib_node*)&snmp_scalar, ...

The pointers must be to const because they are initialized to const objects. 
If this is done corretly, there should be NO casts required on the array
initializers.

So probably:

struct mib_node const * const snmp_nodes[28] = { &snmp_scalar, ...
