Description

COMPONENT_BUILD is defined when generating shared libraries for each project,

Declaration

// 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.
#else  // defined(STARBOARD_IMPLEMENTATION)
#endif
#else  // defined(COMPONENT_BUILD) || SB_IS(LIBRARY)
#define SB_EXPORT
#define SB_EXPORT_PRIVATE
#define SB_IMPORT
#endif  // defined(COMPONENT_BUILD)
#endif  // STARBOARD_EXPORT_H_
