Sets the value for a BLOB column

SE_stream_set_blob sets the value of a BLOB column, which is used when inserting or updating a row in a table or ArcSDE layer.
If the pointer to the SE_BLOB_INFO structure is NULL, a NULL value is set for this column.
The information necessary to insert the BLOB data is supplied in the SE_BLOB_INFO structure.
typedef struct {
LONG blob_length; /* Length in bytes of the BLOB */
CHAR *blob_buffer; /* Linear buffer of BLOB data */
} SE_BLOB_INFO
This function makes a duplicate of the given BLOB buffer and allocates additional memory to contain the BLOB. This can be inefficient when used with large BLOBs. For this situation, you may prefer to use SE_stream_bind_input_column because it does not create a copy of the BLOB. However, be aware that an SE_BIND_CONFLICT error is returned if SE_stream_bind_input_column was called earlier for the specified column or if you call SE_stream_bind_input_column after calling SE_stream_set_blob.
