ieee1284_free_ports — safely deallocate a port list
#include <ieee1284.h>
void ieee1284_free_ports( | list) ; |
struct parport_list
* | list; |
When the port list will no longer be used, the program
should call ieee1284_free_ports
giving
it a pointer to the parport_list
structure that holds the list of ports returned by
ieee1284_find_ports(3). The ports are reference counted with the
ieee1284_open
and
ieee1284_close
functions, and so the
port list may be freed even if it contains pointers to ports
that are still open.
