- o This function sets the total number of columns found in a host
- file for use with bulk copy. This routine may be called only
- after bcp_init() has been called with a valid file name.
- o You should call this routine only if you intend to use a host
- file format that differs from the default. The default host
- file format is described on the bcp_init() manual page.
-
- o After calling bcp_columns(), you must call bcp_colfmt()
- host_colcount times, because you are defining a completely cus-
- tom file format.
- o For information on the bcp utility program, see its manual page
- in the Commands Reference.

- the total number of host file columns.
