Rather than storing ftell(3)'s return value -- a long -- in an
unsigned int, we store and check a properly typed temp. Then, assured a
non-negative value, we store in nBlockPosRet.
fileout << FLATDATA(pchMessageStart) << nSize;
// Write block
- nBlockPosRet = ftell(fileout);
- if (nBlockPosRet == -1)
+ long fileOutPos = ftell(fileout);
+ if (fileOutPos < 0)
return error("CBlock::WriteToDisk() : ftell failed");
+ nBlockPosRet = fileOutPos;
fileout << *this;
// Flush stdio buffers and commit to disk before returning
