rfio_fseek3
Positions/repositions a file
Usage
#include <sys/types.h>
#include "rfio_api.h"
int rfio_fseek (FILE *fp, long offset, int whence);
Under Linux, for large files:
#define _LARGEFILE64_SOURCE
#include <sys/types.h>
#include "rfio_api.h"
int rfio_fseeko64 (FILE *fp, off64_t offset, int whence);
For large files, under other systems:
#include <sys/types.h>
#include "rfio_api.h"
int rfio_fseeko64 (FILE *fp, off64_t offset, int whence);
Overview
rfio_fseek positions/repositions to offset the file associated with the descriptor fp generated by a previous rfio_fopen. whence indicates how to interpret the offset value:
|
The offset is set from beginning of file. |
|---|---|
|
The offset is added to current position. |
|
The offset is added to current file size. |
rfio_fseeko64 can be used with large files and allows to use a 64 bit offset rather than a long.
Return value
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
