udi_pio_unmap(3udi)


Unmap a PIO handle and free associated resources

SYNOPSIS

#include <udi.h>

void udi_pio_unmap (

	udi_pio_handle_t pio_handle );
 

ARGUMENTS pio_handle is the PIO handle to be freed.

DESCRIPTION This service call unmaps a PIO access handle, freeing any associated resources. Upon return pio_handle is no longer valid.

If pio_handle is equal to UDI_NULL_PIO_HANDLE, either explicitly or implicitly (zeroed by initial value or by using udi_memset), this function acts as a no-op. Otherwise, pio_handle must have been allocated by udi_pio_map.
