Access mode for file (MODE_*) |
The named file is opened and a file handle returned. If the accessMode is MODE_OLDFILE, an existing file is opened for reading or writing. If the value is MODE_NEWFILE, a new file is created for writing. MODE_READWRITE opens a file with an shared lock, but creates it if it didn't exist.
The name can be a filename (optionally prefaced by a device name), a simple device such as 'NIL:', a window specification such as 'CON:' or 'RAW:' followed by window parameters, or '*', representing the current window.
If the file cannot be opened for any reason, the value returned will be zero, and a secondary error code will be available by calling the routine IoErr().
