validate_config Subroutine

public subroutine validate_config(cfg, is_valid, message)

Validate that all namelist parameters are physically and numerically sensible.

normalize_config is called first so that scheme names are compared case-insensitively. Three outcomes are possible:

• Error stop (default): if validation fails and neither optional argument is present, error stop is called with a descriptive message.
• Return flag + message: if is_valid and/or message are present, the result is returned in those arguments and execution continues.
• Silent pass: if validation succeeds, is_valid = .true. (when present) and message is set to an empty string (when present).

Arguments

Type	Intent	Optional	Attributes		Name
type(config_t),	intent(inout)			::	cfg	Configuration to validate (normalised in-place).
logical,	intent(out),	optional		::	is_valid	.true. on success, .false. on the first violation found.
character(len=*),	intent(out),	optional		::	message	Human-readable description of the first violation, or ''.
