NAME

6       rfio_fseek - positions/repositions a file
7

SYNOPSIS

9       #include <sys/types.h>
10       #include "rfio_api.h"
11
12       int rfio_fseek (FILE *fp, long offset, int whence);
13
14       Under Linux, for large files:
15       #define _LARGEFILE64_SOURCE
16       #include <sys/types.h>
17       #include "rfio_api.h"
18
19       int rfio_fseeko64 (FILE *fp, off64_t offset, int whence);
20
21       For large files, under other systems:
22       #include <sys/types.h>
23       #include "rfio_api.h"
24
25       int rfio_fseeko64 (FILE *fp, off64_t offset, int whence);
26

DESCRIPTION

28       rfio_fseek positions/repositions to offset the file associated with the
29       descriptor fp generated by a previous rfio_fopen.  whence indicates how
30       to interpret the offset value:
31
32              SEEK_SET     The offset is set from beginning of file.
33
34              SEEK_CUR     The offset is added to current position.
35
36              SEEK_END     The offset is added to current file size.
37       rfio_fseeko64  can  be used with large files and allows to use a 64 bit
38       offset rather than a long.

RETURN VALUE

41       This routine returns 0 if the operation was successful  or  -1  if  the
42       operation failed. In the latter case, serrno is set appropriately.
