_llseek − reposition read/write file offset
_llseek(unsigned int fd, unsigned long
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.
fd is not an open file descriptor.
Problem with copying results to user space.
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 syscall(2).
