After successfully reading from a blob sequentially to a buffer in Objective C
the buffer seems to be altered such that it can no longer be accessed from
memory.... Is there some kind of special buffer type that I should be using?
Here is sample of my code:
int success;
NSData *inBuffer;
success = sqlite3_blob_read(blobData, inBuffer, intByteCount, intOffsetInBlob);
After running this code, success == SQLITE_OK. Prior to reading the blob,
inBuffer behaves normally. Afterward, it no longer behaves like a buffer, and I
cannot get any valid data from it. I have set intByteCount to make sure it is
smaller than the number of bytes in the Blob, and intOffsetInBlob = 0.
Thanks for any help.
