Create a dba_file structure.
- Parameters
-
type | The type of data contained in the file. If -1 is passed, then create will attempt to autodetect the file type from its first byte. |
name | The name of the file to access. "(stdin)", "(stdout)" and "(stderr)" are special file names, that will use the corresponding stream instead of open a file. |
mode | The opening mode of the file, as used by fopen. |
- Returns
- The newly allocated File, that needs to be deleted by the caller.
