DWORD CECompress(LPBYTE  lpbSrc, DWORD cbSrc, LPBYTE lpbDest, DWORD cbDest, WORD wStep, DWORD dwPagesize);


DWORD outlength= inlength-1;
BYTE *outdata= malloc(outlength);
res= CECompress(indata, inlength, outdata, outlength, 1, 4096);
if (res==0xFFFFFFFF) {
   free(outdata);
   // data does not become shorter when compressed
   return NULL;
}
else {
   return outdata;


the outlength being 1 shorter, ensures that it only compresses when the result is shorter.
