ha_open(), ha_open64()
Open a connection and attach it to the HA lib
Synopsis:
#include <ha/fcntl.h>
int ha_open(const char *path,
int oflag,
RFp rfn,
void *rhdl,
unsigned haflags, ...);
int ha_open64(const char *path,
int oflag,
RFp rfn,
void *rhdl,
unsigned haflags, ...);
Library:
libha
Description:
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.
Returns:
A new connection ID or -1 if an error occurred (errno is set).
Errors:
The ha_open() call returns errors as returned by either the underlying open() call or the ha_attach() call.
