#include <sys/types.h>#include <unistd.h>int _llseek(unsigned int fd, unsigned long offset_high, unsigned long offset_low, loff_t *result, unsigned int whence);
DESCRIPTION
The
_llseek()
function repositions the offset of the open file associated
with the file descriptor
fd
to
(offset_high<<32) | offset_low
bytes relative to the beginning of the file, the current position in the file,
or the end of the file, depending on whether
whence
is
SEEK_SET,
SEEK_CUR,
or
SEEK_END,
respectively.
It returns the resulting file position in the argument
result.
RETURN VALUE
Upon successful completion,
_llseek()
returns 0.
Otherwise, a value of -1 is returned and
errno
is set to indicate the error.
ERRORS
EBADF
fd
is not an open file descriptor.
EFAULT
Problem with copying results to user space.
EINVAL
whence
is invalid.
CONFORMING TO
This function is Linux-specific, and should not be used in programs
intended to be portable.
