IDL43 — Feature macros to guard building blocks

  • Key: IDL43-44
  • Status: open  
  • Source: MIT/Lincoln Laboratory ( Mr. Daniel Herring)
  • Summary:

    Now that IDL is modular with building blocks, IDL authors need a way of guarding IDL files so they are compatible with tools that implement different subsets of the building blocks. See discussion in IDL43-21 for a motivating example.

    See C++ feature test macros for a possible implementation pattern.

    Another option is to have an "IDL_VERSION" macro that can be used as a pre-processor condition.
