1003 | * This function allocates a free C Runtime file handle and associates |
1004 | * it with the Win32 HANDLE specified by the first parameter. This is a |
1005 | * temperary fix for WIN95's brain damage GetFileType() error on socket |
1006 | * we just bypass that call for socket |
1007 | * |
1008 | *Entry: |
1009 | * long osfhandle - Win32 HANDLE to associate with C Runtime file handle. |
1010 | * int flags - flags to associate with C Runtime file handle. |
1011 | * |
1012 | *Exit: |
1013 | * returns index of entry in fh, if successful |
1014 | * return -1, if no free entry is found |
