5-12 Neuron C Compiler Errors (NCC)

NCC# Description

68 Message event code must be in range 0..127 [NCC#68]

The event msg_arrives accepts one optional parameter, which is a

message event code. This code must be a compile-time constant

integer expression with a value from 0 to 127, inclusive.

69 Parameter must be a msg_tag [NCC#69]

The events msg_completes, msg_succeeds, and msg_fails all

accept one optional parameter, which must have previously been

declared as a message tag.

Parameter must be an I/O object name [NCC#70]

I/O events only apply to input objects [NCC#71]

Incorrect I/O object type for changes-by event [NCC#72]

Incorrect I/O object type for changes-to event [NCC#73]

Incorrect I/O object type for I/O update-occurs event [NCC#74]

Too many I/O object change events used [NCC#75]

The Neuron C event expressions for io_update_occurs and

io_changes (with its various options) only apply to I/O objects that

are inputs. Furthermore, some events are not applicable to some

input object types. Only one form of event expression can be used

per I/O object. A maximum of 15 I/O objects can have

io_update_occurs and io_changes events. The syntax of the event

expressions requires the event type to be followed by the object

name, in parentheses. For more information, see the I/O Objects

chapter of the Neuron C Reference Guide.

Event ‘nv_update_occurs’ only applies to input variables

[NCC#76]

The nv_update_occurs event accepts one optional parameter,

which must be the name of a previously declared input network

variable.

77 Parameter must be a network variable [NCC#77]

The nv_update_completes, nv_update_fails, and

nv_update_succeeds events all accept one optional parameter,

which must be the name of a previously declared network variable.

78 Parameter must be a timer name [NCC#78]

The event timer_expires accepts one optional parameter, which, if

supplied, must be the name of a previously declared timer object.

79 Invalid use of VOID type [NCC#79]

The void type has no size. It cannot be used as an argument of the

sizeof operator, nor can it be used to declare a variable. Its only

legal uses are in declaring function return types, declaring that a

function has no parameters, and in combination with * to define a

type void * (a wildcard pointer type).

80 Use only 4800, 2400, 1200, or 600 for I/O object’s baud [NCC#80]

The serial I/O object type can only have a bit rate value of 600, 1200,

2400, or 4800. The bit rate value defaults to 2400 if not specified.
