VARGSIZE
VARGSIZE returns the number of bytes that a variable would occupy on the stack if it were passed BYVALUE.
- x
- A variable of any data type, data organization, alignment, and
storage class, except as listed below. x cannot be:
- A BASED, DEFINED, parameter, subscripted, or structure or union base-element variable that is an unaligned fixed-length bit string
- A minor structure or union whose first or last base element is an unaligned fixed-length bit string (except where it is also the first or last element of the containing major structure or union)
- A major structure or union that has the BASED, DEFINED, or parameter attribute, and which has an unaligned fixed-length bit string as its first or last element
- A variable not in connected storage
VARGSIZE(x) returns the number of bytes that x would occupy on the stack if it were passed BYVALUE. This value will be at least as large as SIZE(x); it will be larger if the value returned by SIZE(x) needs to be rounded up to a 4-byte multiple.
VARGSIZE is meant to be used only inside a procedure whose last parameter has the LIST attribute.
