MODULE module_internal_header_util ! !
! Subroutines defined in this module are used to generate (put together) and get (take apart) 
! data headers stored in the form of integer vectors.
! 
! Data headers serve two purposes:  
!   - Provide a package-independent metadata storage and retrieval mechanism 
!     for I/O packages that do not support native metadata.  
!   - Provide a mechanism for communicating I/O commands from compute 
!     tasks to quilt tasks when I/O quilt servers are enabled.  
! 
! Within a data header, character strings are stored one character per integer.  
! The number of characters is stored immediately before the first character of 
! each string.
!
! In an I/O package that does not support native metadata, routines 
! int_gen_*_header() are called to pack information into data headers that 
! are then written to files.  Routines int_get_*_header() are called to 
! extract information from a data headers after they have been read from a 
! file.  
!
! When I/O quilt server tasks are used, routines int_gen_*_header() 
! are called by compute tasks to pack information into data headers 
! (commands) that are then sent to the I/O quilt servers.  Routines 
! int_get_*_header() are called by I/O quilt servers to extract 
! information from data headers (commands) received from the compute 
! tasks.
