SYNOPSIS

function anything_to_bytes(anything) result(chars)

    class(*),intent(in)  :: anything
            or
    class(*),intent(in)  :: anything(:)

    character(len=1),allocatable :: chars(:)

DESCRIPTION

This function uses polymorphism to allow input arguments of different types. It is used to create other procedures that can take many argument types as input options and convert them to a single type to simplify storing arbitrary data, to simplify generating data hashes, ...

OPTIONS

VALUEIN
	input array or scalar to convert to type CHARACTER(LEN=1). May be of KIND INTEGER(kind=int8), INTEGER(kind=int16), INTEGER(kind=int32), INTEGER(kind=int64), REAL(kind=real32, REAL(kind=real64), REAL(kind=real128), complex, or CHARACTER(len=*)

RETURN

CHARS	The returned value is an array of bytes (character(len=1)).

EXAMPLE

Sample program

   program demo_anything_to_bytes
   use M_anything,      only : anything_to_bytes
   implicit none
   integer :: i
      write(*,’(/,4(1x,z2.2))’)anything_to_bytes([(i*i,i=1,10)])
      write(*,’(/,4(1x,z2.2))’)anything_to_bytes([11.11,22.22,33.33])
      write(*,’(/,4(1x,z2.2))’)anything_to_bytes(’This is a string’)
   end program demo_anything_to_bytes
