This is a// placeholder used while constructing an object, and the function// should never actually get called. There is a default// implementation in libsupc++ but that has dependencies on I/O// and so on, unwanted in a minimal eCos environment. Instead we// want a minimal __cxa_pure_virtual().////####DESCRIPTIONEND####////==========================================================================#include <pkgconf/infra.h>#include <cyg/infra/cyg_ass.h>extern "C" void__cxa_pure_virtual(void){ CYG_FAIL("attempt to use a virtual function before object has been constructed"); for ( ; ; );}// EOF pure.cxx
