 +======Synopsis:​======
 +$[[frewind]](<​file descriptor>​)
 +
 +======Technical:​======
 +This function resets the file pointer back to the beginning of the file.  ​
 +The next [[read]] or [[readb]] in the file after this call will read the 
 +first line of the file.
 +
 +This function returns the [[ferror]] 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]]
 + ​0 ​  The file pointer was reset to the beginning
 + ​1 ​  The file pointer could not be reset.
 +</​file>​
