function nf90_inq_var_deflate(ncid, varid, shuffle, deflate, deflate_level)
integer, intent(in) :: ncid
integer, intent(in) :: varid
integer, intent(out) :: shuffle
integer, intent(out) :: deflate
integer, intent(out) :: deflate_level
integer :: nf90_inq_var_deflate
NCID- NetCDF ID, from a previous call to NF90_OPEN or NF90_CREATE.
VARID- Variable ID.
