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.
