129 | *int _patch_open_osfhandle(long osfhandle, int flags) - open C Runtime file handle |
130 | * |
131 | *Purpose: |
132 | * This function allocates a free C Runtime file handle and associates |
133 | * it with the Win32 HANDLE specified by the first parameter. This is a |
134 | * temperary fix for WIN95's brain damage GetFileType() error on socket |
135 | * we just bypass that call for socket |
136 | * |
137 | *Entry: |
138 | * long osfhandle - Win32 HANDLE to associate with C Runtime file handle. |
139 | * int flags - flags to associate with C Runtime file handle. |
140 | * |
141 | *Exit: |
142 | * returns index of entry in fh, if successful |
143 | * return -1, if no free entry is found |
144 | * |
145 | *Exceptions: |
