udi_dma_constraints_attr_reset(3udi)


Reset a constraints attribute to default

SYNOPSIS

#include <udi.h>

void udi_dma_constraints_attr_reset (

	udi_dma_constraints_t constraints,

	udi_dma_constraints_attr_t attr_type );
 

ARGUMENTS constraints is a constraints handle for the constraints object to be modified.

attr_type is the attribute to reset.

DESCRIPTION udi_dma_constraints_attr_reset is used to reset a constraints attribute back to its default value (which is also usually the least restrictive). This is usually needed when a particular module provides special handling relative to the constraints attribute such that any restrictions imposed by parent or child drivers are not transferred through this driver.
