Variable Declarations
The following is ANSI C variable declaration syntax.
variable-declaration-list :
variable-declaration-list variable-declaration ;
variable-declaration ;
variable-declaration :
declaration-specifier-list variable-list
declaration-specifier-list
The variable declaration can declare more than one variable in a comma-
separated list. A network variable can also optionally include a property list
declaration after the variable name (and the variable initializer, if present).

variable-list , extended-variable
extended-variable

Declaration Specifiers
The ANSI C declaration specifiers are augmented in Neuron C by adding the
connection information, the message tag specifier, configuration property
specifiers, network variable specifiers, and timer type specifiers.
