private subroutine json_file_load(me, filename, unit, destroy_pointer)

Load the JSON data from a file.

Example

     program main
      use json_module
      implicit none
      type(json_file) :: f
      call f%load('my_file.json')
      !...
      call f%destroy()
     end program main

Type Bound

json_file

Arguments

Type IntentOptional Attributes Name
class(json_file), intent(inout) :: me
character(kind=CDK, len=*), intent(in) :: filename

the filename to open
integer(kind=IK), intent(in), optional :: unit
