This is the command nescc-wiring that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
PROGRAM:
NAME
nescc-wiring - check wiring of nesC program
SYNOPSIS
nescc-wiring nesc-xml-file
DESCRIPTION
nescc-wiring is a tool to verify that wiring constraints specified on individual
components are respected in a nesC program. These wiring constraints can specify that an
interface provided or used by a component must be wired at least once, at most once, or
exactly once. If no wiring constraints are violated, nescc-wiring terminates with an exit
status of 0. Otherwise, appropriate error messages are printed and nescc-wiring terminates
with a non-zero exit status.
Wiring constraints are specified by placing @atmostonce(), @atleastonce() and
@exactlyonce() attributes on the relevant interfaces. For instance, writing
module Fun {
provides interface Init @atleastonce();
...
ensures that programs using module Fun must wire its Init interface at least once.
Specifically, when the annotation is placed on a provided interface, there must be the
specified number of paths in the wiring graph from any module to that interface. If the
annotations are placed on a used interface, there must be the specified number of paths in
the wiring graph from the interface to any module.
To use this wiring check tool, you must declare the @atmostonce(), @atleastonce() and
@exactlyonce() attributes in some global header file as follows:
struct @atleastonce() { };
struct @atmostonce() { };
struct @exactlyonce() { };
and you must pass the following options to nescc to create the XML file that you pass to
nescc-wiring:
-fnesc-dump=wiring
-fnesc-dump='interfaces(!abstract())'
-fnesc-dump='referenced(interfacedefs, components)'
-fnesc-dumpfile=nesc-xml-file
Use nescc-wiring online using onworks.net services
