96 Neuron C Compiler Errors (NCC)

NCC# Description

417

Invalid declaration type for ‘properties’ clause [NCC#417]

The Neuron C Version 2 syntax permits nonsense declarations like the

following examples, but the compiler later determines that the

nv_properties clause can only apply to a network variable declaration.

Improper uses of the nv_properties clause:

static int abc nv_properties { heartbeatTime };

SNVT_temp_f temperature

nv_properties { heartbeatTime };

Proper use of the nv_properties clause:

network output SNVT_temp_f temperature

nv_properties { heartbeatTime };

In the second "improper use" example above, the declaration may be

confused with a network variable declaration, however, it is not. The

declaration actually is just a variable declaration using the type of the

SNVT (this is a legitimate declaration, but not a network variable, so it

cannot have a property list).

418

Cannot have multiple ‘properties’ clauses on a variable [NCC#418]

The Neuron C Version 2 syntax permits nonsense declarations like the

following example, but the compiler later determines that there are too

many properties clauses in the declaration.

Improper use of the nv_properties clause:

network output SNVT_temp_f temperature

nv_properties { heartbeatTime }

nv_properties { defaultOutput };

The properties clause is a comma-separated list, and corrected use of the

declaration above is shown below:

network output SNVT_temp_f temperature

nv_properties { heartbeatTime,

defaultOutput };

419

A ‘cp’ network variable cannot be an ‘output’ NV [NCC#419]

Configuration property network variables can only be declared as input

network variables. See the chapter describing the use of configuration

properties in the

Neuron C Programmer's Guide

420

Network variable’s property is a duplicate [NCC#420]

The

LONMARK

Application Layer Interoperability Guidelines

specify that

no more than one property of any particular SCPT or UCPT type may be

used for a network variable. Consult that document for more information.
