rfio_fopen64 (3)

#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);

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).

This routine returns NULL if the operation failed or a non-NULL pointer to a FILE structure if the operation was successful. If it fails, serrno variable is set appropriately.

On Irix, Tru64 and IA64 the 64 bit mode is the default one, rfio_fopen and rfio_fopen64 are identical.
