Example
The following example opens for editing a single file specified by a parameter, deletes a character, and closes the edit session three times. The first time, the routine calls _EdCloseFile( ) with the "Immediately save" option, the second time with the "Save after dialog box" option, and the third time with the "Open Save As dialog box" option. Each time, the routine shows the return value of _EdCloseFile( ).
