Removes an I/O mapping segment.
#include <sys/adspace.h>
void io_map_clear (io_handle)
io_handle_t io_handle;
This service destroys all mappings defined by the io_handle_t parameter.
There should be no active mappings (outstanding io_map calls) to this handle when io_map_clear is called. The segment previously created by an io_map_init call or multiple io_map_init calls, is deleted.
