_llseek - reposition read/write file offset
int _llseek(unsigned int fd, unsigned long offset_high,
unsigned long offset_low, loff_t *result,
unsigned int whence);
Note: There is no glibc wrapper for this system call; see NOTES.
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.
Upon successful completion, _llseek() returns 0. Otherwise, a value of
-1 is returned and errno is set to indicate the error.
EBADF fd is not an open file descriptor.
EFAULT Problem with copying results to user space.
EINVAL whence is invalid.
This function is Linux-specific, and should not be used in programs
intended to be portable.
Glibc does not provide a wrapper for this system call; call it using
