 +======Synopsis:​======
 +$[[fseek]](//​file descriptor//​ //​position//​ //anchor//)
 +
 +======Technical:​======
 +This function resets the file pointer to //​position//​ bytes away from 
 +//​anchor//​. ​ The next [[read]] or [[readb]] of the file after this call
 +will read the data from the new location.
 +
 +//​Position//​ can be positive or negative, and //Anchor// must be one of
 +| SET | The beginning of the file |
 +| CUR | The current place in the file |
 +| END | The end of the file | 
 +
 +This function returns the fseek(3) value, which is zero if the operation
 +succeeds and is non-zero if an error occurs.
 +
 +The //file descriptor//​ must have been a value previously returned by 
 +the [[open]] function. ​
 +
 +======Returns:​======
 +<​file>​
 +-1   ​Error:​ //file descriptor//​ was not previously returned by [[open]], or //anchor// is not supported.
 + ​0 ​  The file pointer was reset.
 + ​1 ​  The file pointer could not be reset.
 +</​file>​
