NAME

       erl_internal - Internal Erlang Definitions

DESCRIPTION

       This module defines Erlang BIFs, guard tests and operators. This module is only of interest to programmers who manipulate Erlang code.

EXPORTS

       bif(Name, Arity) -> bool()

	      Types  Name = atom()
		     Arity = integer()

	      Returns true if Name/Arity is an Erlang BIF which is automatically recognized by the compiler, otherwise false .

       guard_bif(Name, Arity) -> bool()

	      Types  Name = atom()
		     Arity = integer()

	      Returns true if Name/Arity is an Erlang BIF which is allowed in guards, otherwise false .

       type_test(Name, Arity) -> bool()

	      Types  Name = atom()
		     Arity = integer()

	      Returns true if Name/Arity is a valid Erlang type test, otherwise false .

       arith_op(OpName, Arity) -> bool()

	      Types  OpName = atom()
		     Arity = integer()

	      Returns true if OpName/Arity is an arithmetic operator, otherwise false .

       bool_op(OpName, Arity) -> bool()

	      Types  OpName = atom()
		     Arity = integer()

	      Returns true if OpName/Arity is a Boolean operator, otherwise false .

       comp_op(OpName, Arity) -> bool()

	      Types  OpName = atom()
		     Arity = integer()

	      Returns true if OpName/Arity is a comparison operator, otherwise false .

       list_op(OpName, Arity) -> bool()

	      Types  OpName = atom()
		     Arity = integer()

	      Returns true if OpName/Arity is a list operator, otherwise false .

       send_op(OpName, Arity) -> bool()

	      Types  OpName = atom()
		     Arity = integer()

	      Returns true if OpName/Arity is a send operator, otherwise false .

       op_type(OpName, Arity) -> Type

	      Types  OpName = atom()
		     Arity = integer()
		     Type = arith | bool | comp | list | send

	      Returns the Type of operator that OpName/Arity belongs to, or generates a function_clause error if it is not an operator at all.
