NAME

       _llseek - reposition read/write file offset

SYNOPSIS

       #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.

NOTES

       Glibc does not provide a wrapper for this system call;  call  it  using
       syscall(2).
