freeOperandStack()

void freeOperandStack

(

OperandStack **

os

)

Free all the elements of the OperandStack passed as parameter by reference.

Parameters

OperandStack**

os - pointer to the OperandStack.

Here is the caller graph for this function:

popOperand()

uint8_t popOperand	(	OperandStack **	os,
		int32_t *	outPtr,
		enum OperandType *	outType
	)

Pop the operand out of the top of OperandStack passed as parameter by reference.

Parameters

OperandStack**	os - pointer to the OperandStack.
int32_t*	outPtr - value of the operand that will be popped.
OperandType	outType - type of the operand that will be popped.

Returns

0 if the pop operation was not successful, 1 otherwise.

pushOperand()

uint8_t pushOperand	(	OperandStack **	os,
		int32_t	value,
		enum OperandType	type
	)

Push the operand on the top of OperandStack passed as parameter by reference.

Parameters

OperandStack**	os - pointer to the OperandStack where the operand will be pushed.
int32_t	value - value of the operand.
OperandType	type - type of the operand that will be pushed

Returns

0 if OperandStack* node is NULL, in other words, if the push was not successful, 1 otherwise
