NAME

rfio_fopen - opens a file  

SYNOPSIS

#include <sys/types.h>
#include "rfio_api.h"

FILE *rfio_fopen (char *path, char *mode);

Under Linux, for large files:
#define _LARGEFILE64_SOURCE
#include <sys/types.h>
#include "rfio_api.h"

FILE *rfio_fopen64 (char *path, char *mode);

For large files, under other systems:
#include <sys/types.h>
#include "rfio_api.h"

FILE *rfio_fopen64 (char *path, char *mode);  

DESCRIPTION

rfio_fopen opens the file whose name is the string pointed to by path , a character string containing the filename specification, and associates a FILE stream with it.

mode is an access mode indicator. One of the characters "r" or "w".

rfio_fopen64 allows to open large files (see NOTES).  

RETURN VALUE
