Macro Definition Documentation

cs_alloc_mode

#define cs_alloc_mode   CS_ALLOC_HOST

cs_associate_device_ptr

#define cs_associate_device_ptr	(		_host_ptr,
			_ni,
			_size
	)		;

Associate device memory with a given host memory pointer.

If the host memory is already associated with the device, the existing device pointer is returned. Otherwise, a new device allocation is called and returned.

Parameters

[in]	host_ptr	host pointer
[in]	ni	number of elements
[in]	size	element size

Returns

pointer to allocated memory.

cs_dissassociate_device_ptr

#define cs_dissassociate_device_ptr

(

_host_ptr

)

;

Detach device memory from a given host memory pointer.

If the host memory is shared with the device (i.e. using CS_ALLOC_SHARED), device memory stays shared.

Parameters

[in]

host_ptr

host pointer

CS_FREE

#define CS_FREE

(

_ptr

)

cs_free(_ptr, #_ptr, __FILE__, __LINE__), _ptr = NULL

CS_FREE_HD

#define CS_FREE_HD

(

_ptr

)

cs_free_hd(_ptr, #_ptr, __FILE__, __LINE__), _ptr = NULL

CS_MALLOC_HD

#define CS_MALLOC_HD	(		_ptr,
			_ni,
			_type,
			_mode
	)

Value:

_ptr = (_type *) cs_malloc_hd(_mode, _ni, sizeof(_type), \
                                   #_ptr, __FILE__, __LINE__)

CS_REALLOC_HD

#define CS_REALLOC_HD	(		_ptr,
			_ni,
			_type,
			_mode
	)

Value:

_ptr = (_type *) cs_realloc_hd(_ptr, _mode, _ni, sizeof(_type), \
                               #_ptr, __FILE__, __LINE__)

cs_set_alloc_mode

#define cs_set_alloc_mode	(		_host_ptr,
			mode
	)		;

Set allocation mode for an already allocated pointer.

If the allocation mode is different from the previous one, the associated memory will be reallocated with the desired mode, and the previous allocation freed.

Parameters

[in,out]	host_ptr	pointer to host pointer to modify
[in]	mode	desired allocation mode
