The lld_tell() function

This function returns the offset for the next read or write operation on an open large object.

Syntax

API
mi_integer lld_tell(conn, io, offset, error)
   MI_CONNECTION*                conn;
   LLD_IO*                       io,
   mi_int8*                      offset;
   mi_integer*                   error;
ESQL/C
int lld_tell (io, offset, error);
   LLD_IO* io;
EXEC SQL BEGIN DECLARE SECTION;
   PARAMETER int8* offset;
EXEC SQL END DECLARE SECTION;
   int* error;
conn
The connection descriptor established by a previous call to the mi_open() or mi_server_connect() functions. This parameter is for the API interface only. In the ESQL/C and SQL versions of this function, you must already be connected to a server.
io
A pointer to an LLD_IO structure created with a previous call to the lld_open() function.
offset
A pointer to an int8 that you allocate. The function returns the offset in this int8.
error
An output parameter in which the function returns an error code.

Usage

Before calling this function, you must open the large object with a call to lld_open().

Return codes

For an API function, returns MI_OK if the function succeeds and MI_ERROR if it fails.

For an ESQL/C function, returns 0 if the function succeeds and -1 if the function fails.
