WM_CAP_FILE_SAVEAS message

The WM_CAP_FILE_SAVEAS message copies the contents of the capture file to another file. You can send this message explicitly or by using the capFileSaveAs macro.



WM_CAP_FILE_SAVEAS 
wParam = (WPARAM) 0; 
lParam = (LPARAM) (LPVOID) (LPSTR) (szName); 


Parameters

szName

Pointer to the null-terminated string that contains the name of the destination file used to copy the file.

Return Value

Returns TRUE if successful or FALSE otherwise.

If an error occurs and an error callback function is set using the WM_CAP_SET_CALLBACK_ERROR message, the error callback function is called.

Remarks

This message does not change the name or contents of the current capture file.

If the copy operation is unsuccessful due to a disk full error, the destination file is automatically deleted.

Typically, a capture file is preallocated for the largest capture segment anticipated and only a portion of it might be used to capture data. This message copies only the portion of the file containing the capture data.
