wxMediaEdit::FindSnip

wxSnip* FindSnip (long pos, int direction, long *sPos = NULL)

  Returns the snip for the given position. If the position is between two snips, direction specifies which snip to return; direction can be any of the following:

•   wxSNIP_BEFORE_OR_NULL -- Returns the snip before the position, or NULL if pos is 0
•   wxSNIP_BEFORE -- Returns the snip before the position, or the first snip if pos is 0
•   wxSNIP_AFTER -- Returns the snip after the position, or the last snip if pos is the last position
•   wxSNIP_AFTER_OR_NULL - Returns the snip after the position, or NULL if pos is the last position

If sPos is non-NULL, then it will be filled with the position at which the returned snip starts.
