| 121 | *int _patch_open_osfhandle(long osfhandle, int flags) - open C Runtime file handle |
| 122 | * |
| 123 | *Purpose: |
| 124 | * This function allocates a free C Runtime file handle and associates |
| 125 | * it with the Win32 HANDLE specified by the first parameter. This is a |
| 126 | * temperary fix for WIN95's brain damage GetFileType() error on socket |
| 127 | * we just bypass that call for socket |
| 128 | * |
| 129 | *Entry: |
| 130 | * long osfhandle - Win32 HANDLE to associate with C Runtime file handle. |
| 131 | * int flags - flags to associate with C Runtime file handle. |
| 132 | * |
| 133 | *Exit: |
| 134 | * returns index of entry in fh, if successful |
| 135 | * return -1, if no free entry is found |
| 136 | * |
| 137 | *Exceptions: |
