◆ gdncvarputattrdouble()

subroutine gdncvarputattrdouble	(	type(gd_nc_variable), intent(in)	var,
		character(len = *), intent(in)	name,
		double precision, dimension(:), intent(in)	value,
		logical, intent(out), optional	err )

Set double precision attribute value

Sets a double precision attribute on a variable. If name starts with '+', it is treated as a global attribute. Empty value array deletes the attribute.

Parameters

[in]	var	Variable handle
[in]	name	Attribute name
[in]	value	Double precision values to set
[out]	err	Error flag (optional)

◆ gdncvarputattrreal()

subroutine gdncvarputattrreal	(	type(gd_nc_variable), intent(in)	var,
		character(len = *), intent(in)	name,
		real, dimension(:), intent(in)	value,
		logical, intent(out), optional	err )

Set real (single precision) attribute value

Sets a real attribute on a variable. If name starts with '+', it is treated as a global attribute. Empty value array deletes the attribute.
