gtvarcopyattr()

subroutine gtvarcopyattr	(	type(gt_variable), intent(inout)	to,
		character(len = *), intent(in)	attrname,
		type(gt_variable), intent(in)	from,
		logical, intent(out), optional	err )

Copy single attribute from one variable to another

Copies attribute attrname of variable from to variable to. If an error occurs during copying, outputs a message and terminates the program. If err is provided, returns .true. in that argument and program does not terminate.

Copy_Attr is a generic name for 2 subroutines; there is also a method to copy all attributes of a variable at once.

Parameters

[in,out]	to	Destination variable handle
[in]	attrname	Attribute name to copy
[in]	from	Source variable handle
[out]	err	Error flag (optional)
