MODULE H5fortkit
CONTAINS
!****if* H5fortkit/HD5c2fstring
! NAME
! HD5c2fstring
! INPUTS
! cstring - C string stored as a string array of size 'len' of string size LEN=1
! len - length of Fortran string
! OUTPUT
! fstring - Fortran string array of LEN=1
! PURPOSE
! Copies a Fortran array of strings having a length of one to a fortran string and removes the C Null
! terminator. The Null terminator is returned from C when calling the C APIs directly.
!
! The fortran standard does not allow C_LOC to be used on a character string of
! length greater than one, which is why we use the array of characters instead.
!
