Literally speaking, not at present. However, you can register a routine to be
called when a file is *opened*, and have that routine free up any old stuff, if
any, remaining from a previous capture. See register_init_routine().
Arguably, there should be separate "initialize" and "finish" routines.
In addition, as Joerg noted, for some purposes you might want to use
Wireshark's memory-chunk allocators and allocate "seasonal" memory ("seasons"
begin when a capture is opened and end when a capture is closed).
