Functions

func C_DeclFragment_Func 

func C_DeclFragment_Func(p *parser.Parser, tokens *scanlist.Element, left interface{}) parser.ParserResult

func RegisterDeclaration 

func RegisterDeclaration(p *parser.Parser)

func RegisterExpr 

func RegisterExpr(p *parser.Parser)

The following expression classes are registered. 

'Expr0' // Primary Expression + Suffix
'Expr1' // Unary Expression
'Expr2' // Cast Expression
'Expr3' // Multiplicative Expression
'Expr4' // Additive Expression
'Expr5' // Bitwise expression
'Expr6' // Relational expression
'Expr7' // Logical expression
'Expr8' // Conditional expression
'Expr'  // Expression

func RegisterExprCast 

func RegisterExprCast(p *parser.Parser)

Should be called only after RegisterExpr()! Adds the casting operation (Type)Expr.

func RegisterStatememt 

func RegisterStatememt(p *parser.Parser)

func RegisterType 

func RegisterType(p *parser.Parser)
