The mi_streamwrite_lo() function

The mi_streamwrite_lo() function writes a smart large object to a stream, converting any difference in the internal representation to that of the stream representation.

Syntax

mi_integer mi_streamwrite_lo(strm_desc, LO_hdl_ptr)
   MI_STREAM *strm_desc;
   MI_LO_HANDLE *LO_hdl_ptr;
strm_desc
A pointer to the stream descriptor for the open stream to which to write the LO handle.
LO_hdl_ptr
A pointer to the LO handle to write to the stream.
Valid in client LIBMI application? Valid in user-defined routine?
No Yes

Usage

The mi_streamwrite_lo() function writes the smart large object that LO_hdl_ptr references to the stream that strm_desc references. The write operation begins at the current stream seek position. You can use mi_stream_tell() or mi_stream_getpos() to obtain this seek position.
Important: The mi_streamwrite_lo() function requires the caller to have an open connection to the database server.

The mi_streamwrite_lo() function is useful in the streamwrite() support function of an opaque data type that contains a smart large object.

For more information about the use of mi_streamwrite_lo() in a streamwrite() support function, see the Informix® DataBlade® API Programmer's Guide.

Return values

>=0
The number of bytes that the function has written to the open stream.
MI_STREAM_EEOF
The end of the stream has been reached.
MI_STREAM_EBADARG
The stream descriptor that strm_desc references or the value that LO_hdl_ptr references is invalid.
MI_ERROR
The function was not successful.
