NAME¶
rfio_fseek - positions/repositions a file
SYNOPSIS¶
#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);
DESCRIPTION¶
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:
- SEEK_SET
- The offset is set from beginning of file.
- SEEK_CUR
- The offset is added to current position.
- SEEK_END
- 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.
ERRORS¶
- EBADF
- fp is not a valid descriptor.
- EINVAL
- incorrect value for whence.
- SENOSHOST
- Host unknown.
- SENOSSERV
- Service unknown.
- SETIMEDOUT
- Timed out.
- SEBADVERSION
- Version ID mismatch.
- SEINTERNAL
- Internal error.
