json_string_info Subroutine

private subroutine json_string_info(json, p, ilen, max_str_len, found)

Returns information about character strings returned from a json_value.

Type Bound

json_core

Arguments

Type IntentOptional Attributes Name
class(json_core), intent(inout) :: json
type(json_value), pointer :: p
integer(kind=IK), intent(out), optional, dimension(:), allocatable :: ilen

if p is an array, this is the actual length of each character string in the array. if not an array, this is returned unallocated.
integer(kind=IK), intent(out), optional :: max_str_len

The maximum length required to hold the string representation returned by a call to a get routine. If a scalar, this is just the length of the scalar. If a vector, this is the maximum length of any element.
logical(kind=LK), intent(out), optional :: found

true if there were no errors. if not present, an error will throw an exception
