HFS ( Hierarchical File System )

I am finding very little information online about accessing the HFS on the
400.

Can someone provide a little help on what I am doing wrong:


#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <qhfopnsf.h>
#include <qhfclosf.h>

typedef struct error_code_struct {
int bytes_provided;
int bytes_available;
char exception_id[7];
char reserved_field;
char exception_data[256];
} error_code_struct;

char path_name[30];
int path_length;
char open_info[10];

char file_handle[16];
char attrib_info;
int attrib_length = 0;
char action;

error_code_struct error_code;

int main ( int argc, char *argv[] )
{

strcpy(path_name,"/QDLS/HFSFLR/SAMPLE.HFS");
path_length = strlen( path_name );

strcpy( open_info, "210 120 " );
printf("OPEN STREAM FILE:\n ");
QHFOPNSF( &file_handle,
path_name,
path_length,
open_info,
&attrib_info,
attrib_length,
&action,
&error_code );

if( error_code.bytes_available > 0 )
{
printf("FAIL -- OPEN STREAM FILE:\n ");
exit( 1 );
}

printf("CLOSE STREAM FILE:\n ");
QHFCLOSF( &file_handle,
&error_code );

if( error_code.bytes_available > 0 )
{
printf("FAIL -- CLOSE STREAM FILE:\n ");
exit( 1 );
}
}


-Thanks
