API Expand.VarName

	VarName
Expands a string to the name of a global variable used in the generated code
- STRING	Source
The variable name to expand
- HANDLE	Owner
A component that owns the variable
- BOOL	SizeName
Set true to return the expanded size define
- BOOL	FullLine
Set true to expand to a full declaration, else just the name
- STRING	Return

Detailed description

This expands a global variable to the name it would be given in the generated code. The size define (the size of the final dimension of the array) may be returned instead if required.

Note this does not return the full expression unless FullLine is true. In this case, Source must be a valid variable name for the Owner component, as the system needs this in order to expand the variable type, array sizes and initialisers.

This is an example of what may be shown with differing SizeName and FullLine values. The sample variable is TestVar, a byte array of 16 elements.

SizeName	FullLine	Result
false	false	FCV_TESTVAR
true	false	FCVsz_TESTVAR
false	true	MX_UINT8 FCV_TESTVAR[FCVsz_TESTVAR]
true	true	#define FCVsz_TESTVAR 16

Examples

Calling in a calculation

• Declare a variable 'result' of type STRING
• Add to a calculation icon:

  result = ::Expand.VarName("source", owner, false, true)
