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.
