Function/Subroutine Documentation

gtvarclose()

subroutine gtvarclose	(	type(gt_variable), intent(in), target	var,
		logical, intent(out), optional	err
	)

Finalize variable

Performs finalization for variable var. Variables that have been Opened or Created must be finalized using this subroutine at the end of the program.

If an error occurs during finalization, outputs a message and terminates the program. If err is provided, returns .true. in that argument and program does not terminate.

Parameters

[in]	var	Variable handle to close
[out]	err	Error flag (optional)
