R-08195-21952-34144-42523-58914-33404-63629-47185 tcl slt th3 src
This function is used to read data from an open BLOB handle into a caller-supplied buffer. N bytes of data are copied into buffer Z from the open BLOB, starting at offset iOffset.

If offset iOffset is less than N bytes from the end of the BLOB, SQLITE_ERROR is returned and no data is read.

R-35711-48727-49492-05161-09107-16114-44571-60110 tcl slt th3 src
If N or iOffset is less than zero, SQLITE_ERROR is returned and no data is read.

The size of the blob (and hence the maximum value of N+iOffset) can be determined using the sqlite3_blob_bytes() interface.

An attempt to read from an expired BLOB handle fails with an error code of SQLITE_ABORT.

On success, sqlite3_blob_read() returns SQLITE_OK. Otherwise, an error code or an extended error code is returned.
