1412* This function allocates a free C Runtime file handle and associates
1413* it with the Win32 HANDLE specified by the first parameter. This is a
1414* temperary fix for WIN95's brain damage GetFileType() error on socket
1415* we just bypass that call for socket
1416*
1417*Entry:
1418* long osfhandle - Win32 HANDLE to associate with C Runtime file handle.
1419* int flags - flags to associate with C Runtime file handle.
1420*
1421*Exit:
1422* returns index of entry in fh, if successful
1423* return -1, if no free entry is found
1424*
