◆ expandArgs()

void expandArgs	(	RexxObject **	arguments,
		size_t	argcount,
		size_t	min,
		size_t	max,
		const char *	function
	)

Verify that a function has received all of its required arguments, and did not receive extras.

Parameters

argcount	The number of arguments passed to the function.
min	The minimum required arguments
max	The maximum required arguments
function	The function name

Returns: Nothing.

Definition at line 75 of file BuiltinFunctions.cpp.

References Error_Incorrect_call_maxarg, Error_Incorrect_call_minarg, Error_Incorrect_call_noarg, min, OREF_NULL, and reportException().

◆ optionalBigIntegerArg()

RexxObject* optionalBigIntegerArg	(	size_t	position,
		RexxObject **	arguments,
		size_t	argcount,
		const char *	function
	)

Process an optional argument and ensure it is a valid integer that can be expressed as a 64-bit value.

Parameters

position	The argument position for any error messages (1 to argcount).
argcount	The number of arguments passed to the function.
function	The function name

Returns: An object that can be converted to a 64-bit value for pass-on to a native function.

Definition at line 283 of file BuiltinFunctions.cpp.

References Error_Incorrect_call_whole, Numerics::int64Object(), OREF_NULL, and reportException().

◆ optionalIntegerArg()

RexxInteger* optionalIntegerArg	(	size_t	position,
		RexxObject **	arguments,
		size_t	argcount,
		const char *	function
	)

Process an optional argument and ensure it is a valid integer

Parameters

position	The argument position for any error messages (1 to argcount).
argcount	The number of arguments passed to the function.
function	The function name

Returns: An object that can be converted to an integer argument.

◆ optionalStringArg()

RexxString* optionalStringArg	(	size_t	position,
		RexxObject **	arguments,
		size_t	argcount,
		const char *	function
	)

Process an optional argument and potentially convert it into a string argument

Parameters

position	The argument position for any error messages (1 to argcount).
argcount	The number of arguments passed to the function.
function	The function name

Returns: The string representation of the argument.
