-* This function allocates a free C Runtime file handle and associates
-* it with the Win32 HANDLE specified by the first parameter. This is a
-* temperary fix for WIN95's brain damage GetFileType() error on socket
-* we just bypass that call for socket
-*
-* This works with MSVC++ 4.0+ or GCC/Mingw32
-*
-*Entry:
-* intptr_t osfhandle - Win32 HANDLE to associate with C Runtime file handle.
-* int flags - flags to associate with C Runtime file handle.
-*
-*Exit:
-* returns index of entry in fh, if successful
-* return -1, if no free entry is found
-*
-*Exceptions:
-*
-*******************************************************************************/
