Piotr Caban (@piotr) commented about dlls/msvcrt/tests/file.c:
+ ok(stdout==stdin+1, "msvcrt stdout FILE must be adject to stdin"); + ok(_IOMYBUF == 0x0008, "MSVCRT _IOBUFFER_CRT should be 0x0008"); +#endif + + tempf = _tempnam(".","wne"); + file = fopen(tempf, "wb"); + + fprintf(file, "%s", "Hello World\n"); + ptrold = file->_ptr; + cntold = file->_cnt; + if (ptrold && cntold) + { + fprintf(file, "%s", "Hello"); + ok(ptrold + 5 == file->_ptr, "FILE _ptr incorrect"); + ok(cntold - 5 == file->_cnt, "FILE _cnt incorrect"); + ok(ptrold + cntold == file->_ptr + file->_cnt, "FILE _ptr or _cnt incorrect"); This test is redundant, your checking it in earlier tests.
