1017 | * This function allocates a free C Runtime file handle and associates | |
1018 | * it with the Win32 HANDLE specified by the first parameter. This is a | |
1019 | * temperary fix for WIN95's brain damage GetFileType() error on socket | |
1020 | * we just bypass that call for socket | |

1022 | *Entry: | |
1023 | * long osfhandle - Win32 HANDLE to associate with C Runtime file handle. | |
1024 | * int flags - flags to associate with C Runtime file handle. | |
1025 | * | |
1026 | *Exit: | |
1027 | * returns index of entry in fh, if successful | |
1028 | * return -1, if no free entry is found | |
