Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The getw function reads the next binary value of type int from the
     file associated with <stream>. It then increments the associated
     file pointer (if there is one) to point to the next unread
     character. The getw function does not assume any special alignment
     of items in the stream.
 
     Return Value
 
     The getw function returns the integer value read. A return value
     of EOF may indicate an error or end-of-file. However, the EOF
     value is also a legitimate integer value, so feof or ferror should
     be used to verify an end-of-file or error condition.
 
     NOTE: The getw function is provided primarily for compatibility
           with previous libraries. Portability problems may occur with
           getw, since the size of int and the ordering of bytes within
           int differ across systems.
