Saving
Captured Data to a New File
If the user
wants to save captured data, the application should save the contents of the
capture file to another file by using the WM_CAP_FILE_SAVEAS message (or the capFileSaveAs macro). This message does
not change the name or contents of the capture file. Your application must
specify a name for the new file because the capture file retains its original
filename.
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 capture file containing the capture data.
