rfio_lseek - positions/repositions a file
#include <sys/types.h>
#include "rfio_api.h"
off_t rfio_lseek (int s, off_t offset, int how);
Under Linux, for large files:
#define _LARGEFILE64_SOURCE
#include <sys/types.h>
#include "rfio_api.h"
off64_t rfio_lseek64 (int s, off64_t offset, int how);
For large files, under other systems:
#include <sys/types.h>
#include "rfio_api.h"
off64_t rfio_lseek64 (int s, off64_t offset, int how);
rfio_lseek positions/repositions to offset the file associated with the descriptor s generated by a previous rfio_open. how indicates how to interpret the offset value:
rfio_lseek64 performs the same function on large files using off64_t rather than off_t.
This routine returns -1 if the operation failed or the actual offset from the beginning of file. In case of failure, serrno is set appropriately.
