// Annotate the declarations of deprecated functions with this to cause a
|
|
// compiler warning when they're used. Like so:
|
|
//
|
|
// RTC_DEPRECATED std::pony PonyPlz(const std::pony_spec& ps);
|
|
//
|
|
// NOTE 1: The annotation goes on the declaration in the .h file, not the
|
|
// definition in the .cc file!
|
|
//
|
|
// NOTE 2: In order to keep unit testing the deprecated function without
|
|
// getting warnings, do something like this:
|
|
//
|
|
// std::pony DEPRECATED_PonyPlz(const std::pony_spec& ps);
|
|
// RTC_DEPRECATED inline std::pony PonyPlz(const std::pony_spec& ps) {
|
|
// return DEPRECATED_PonyPlz(ps);
|
|
// }
|
|
//
|
|
// In other words, rename the existing function, and provide an inline wrapper
|
|
// using the original name that calls it. That way, callers who are willing to
|
|
// call it using the DEPRECATED_-prefixed name don't get the warning.
|
|
//
|
|
// TODO(kwiberg): Remove this when we can use [[deprecated]] from C++14.
