Open a connection and attach it to the HA lib
#include <ha/fcntl.h>
int ha_open(const char *path,
int oflag,
RFp rfn,
void *rhdl,
unsigned haflags, ...);
int ha_open64(const char *path,

In addition to opening the connection using the standard
open|64() call, these convenience functions also
call ha_attach() with the connection returned by
the open() call.
The parameters rfn(), and rhdl(), and
haflags() are passed to the ha_attach() call along
with the connection ID returned by the open() call.
The remaining parameters are passed to the corresponding
parameters in the open() call in their
appropriate positions.
A new connection ID or -1 if an error occurred (errno is set).
The ha_open() call returns errors as returned by
either the underlying open() call or the
ha_attach() call.
