Open a file stream and attach it to the HA lib
#include <ha/stdio.h> int ha_fopen(const char *path, const char *mode, RFp rfn, void *rhdl, unsigned haflags);
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.
A pointer to a file stream or NULL if an error occurs (errno is set).
The ha_fopen() call returns errors as returned by either the underlying fopen() call or the ha_attach() call.
