This function frees the storage allocated by the file dialog when the dialog flag is set.
Syntax
WinFreeFileDlgList(papszFQFilename);
Parameters
- papszFQFilename (PAPSZ) - input
- Pointer to a table of pointers of fully-qualified file names returned by the dialog.
Returns
- rc (BOOL) - returns
- Success indicator.
- TRUE
- Successful completion.
- FALSE
- Error occurred.
Remarks
When the style flag is set and the user selects one or more files from the file name list box, the fully-qualified file names of the selected files are returned in the field of the FILEDLG structure. After the application retrieves all of the information it needs from the array, it should call WinFreeFileDlgList to free the storage.
Example Code
This example uses the WinFreeFileDlgList function to deallocate the table of file name pointers returned by the WinFileDlg function when the field of the FILEDLG structure.
#define INCL_WINSTDFILE /* Window Standard File Functions */ #include <os2.h> BOOL fSuccess; /* Success indicator */ FILEDLG pfdFiledlg; /* File dialog info structure */ HWND hwndMain; /* Window that owns the file dialog */ HWND hwndDlg; /* File dialog window */ /*****************************************************************/ /* initialize FILEDLG structure */ /*****************************************************************/ pfdFiledlg.cbSize = sizeof(FILEDLG); /* Size of structure */ pfdFiledlg.fl = FDS_MULTIPLESEL | FDS_HELPBUTTON | FDS_CENTER | FDS_OPEN_DIALOG; /* FDS_* flags */ /*****************************************************************/ /* Set remaining fields here */ /*****************************************************************/ . . . /*****************************************************************/ /* Display the dialog and get the files */ /*****************************************************************/ hwndDlg = WinFileDlg(HWND_DESKTOP, hwndMain, &pfdFiledlg); if (hwndDlg && (pfdFiledlg.lReturn == DID_OK)) { /**************************************************************/ /* Upon successful return of the files, open them for further */ /* processing using the table of file name pointers */ /**************************************************************/ /**************************************************************/ /* Find out whether the pointer array was allocated */ /**************************************************************/ if (pfdFiledlg.papszFQFilename) /***********************************************************/ /* If so, free the table of file name pointers */ /***********************************************************/ fSuccess = WinFreeFileDlgList(pfdFiledlg.papszFQFilename); }
