| // COMPONENT_BUILD is defined when generating shared libraries for each project, |
| // rather than static libraries. This means we need to be careful about |
| // EXPORT/IMPORT. |
| // SB_IS_LIBRARY is defined when building Starboard as a shared library to be |
| // linked into a client app. In this case, we want to explicitly define |
| // EXPORT/IMPORT so that Starboard's symbols are visible to such clients. |
| #if defined(STARBOARD_IMPLEMENTATION) |
| // STARBOARD_IMPLEMENTATION is defined when building the Starboard library |
| // sources, and shouldn't be defined when building sources that are clients of |
| // Starboard. |
