ha_fopen()

Open a file stream and attach it to the HA lib

Synopsis:

#include <ha/stdio.h>
    
int ha_fopen(const char *path, 
             const char *mode,
             RFp rfn, 
             void *rhdl, 
             unsigned haflags);

Library:

libha

Description:

In addition to opening the connection using the standard fopen() call, this convenience function also calls ha_attach() with the connection returned by the fopen() call.

The parameters rfn(), and rhdl(), and haflags() are passed to the ha_attach() call along with the connection ID returned by the underlying fopen() call.

The remaining parameters are passed to the corresponding parameters in the fopen() call in their appropriate positions.

Returns:

A pointer to a file stream or NULL if an error occurs (errno is set).

Errors:

The ha_fopen() call returns errors as returned by either the underlying fopen() call or the ha_attach() call.

Classification:

QNX Neutrino
