GCC attribute macros

QNX SDP8.0QNX Helpers Developer's GuideAPIDeveloper

Convenience macros that make it easier to use some of the options provided by the GCC keyword attribute.

Description:

The tasks these macros perform include managing attribute support for the different GCC versions and specifying whether the code to compile uses GCC (which is required to use attribute).

If the GCC version doesn't support attribute, these macros revert to being empty.

For more information about specific attributes, go to https://gcc.gnu.org/onlinedocs/.
