NAME +! Executable: H5test_kind +! +! FILE +! fortran/src/H5test_kind_STORAGE_SIZE.f90 +! +! PURPOSE +! This stand alone program is used at build time to generate the program +! H5fortran_detect.f90. It cycles through all the available KIND parameters for +! integers and reals. The appropriate program and subroutines are then generated +! depending on which of the KIND values are found. +! +! NOTES +! This program is used in place of H5test_kind.f90 or H5test_kind_SIZEOF.f90 when +! the Fortran 2008 intrinsic function STORAGE_SIZE is available. It generates code +! that makes use of STORAGE_SIZE in H5fortran_detect.f90, which will be standard +! compliant. This program is the preferred method. +! +! The availability of STORAGE_SIZE is checked at configure time and the TRUE/FALSE +! condition is set in the configure variable "FORTRAN_HAVE_STORAGE_SIZE". +! +! The use of C_SIZOF(X) is not used since the argument X must be an interoperable +! data entity. +! +! COPYRIGHT +! * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * +!
