Memory management (deprecated)#

hipError_t hipMallocHost(void **ptr, size_t size)#

Allocate pinned host memory [Deprecated].

If size is 0, no memory is allocated, *ptr returns nullptr, and hipSuccess is returned.

Warning

This API is deprecated, use hipHostMalloc() instead

Parameters:

  • ptr – [out] Pointer to the allocated host pinned memory

  • size – [in] Requested memory size

Returns:

hipSuccess, hipErrorOutOfMemory

hipError_t hipMemAllocHost(void **ptr, size_t size)#

Allocate pinned host memory [Deprecated].

If size is 0, no memory is allocated, *ptr returns nullptr, and hipSuccess is returned.

Warning

This API is deprecated, use hipHostMalloc() instead

Parameters:

  • ptr – [out] Pointer to the allocated host pinned memory

  • size – [in] Requested memory size

Returns:

hipSuccess, hipErrorOutOfMemory

hipError_t hipHostAlloc(void **ptr, size_t size, unsigned int flags)#

Allocate device accessible page locked host memory [Deprecated].

If size is 0, no memory is allocated, *ptr returns nullptr, and hipSuccess is returned.

Warning

This API is deprecated, use hipHostMalloc() instead

Parameters:

  • ptr – [out] Pointer to the allocated host pinned memory

  • size – [in] Requested memory size in bytes

  • flags – [in] Type of host memory allocation

Returns:

hipSuccess, hipErrorOutOfMemory

hipError_t hipFreeHost(void *ptr)#

Free memory allocated by the hcc hip host memory allocation API [Deprecated].

Warning

This API is deprecated, use hipHostFree() instead

Parameters:

ptr – [in] Pointer to memory to be freed

Returns:

hipSuccess, hipErrorInvalidValue (if pointer is invalid, including device pointers allocated with hipMalloc)

hipError_t hipMemcpyToArray(hipArray_t dst, size_t wOffset, size_t hOffset, const void *src, size_t count, hipMemcpyKind kind)#

Copies data between host and device.

Warning

This API is deprecated.

Parameters:

  • dst – [in] Destination memory address

  • wOffset – [in] Destination starting X offset

  • hOffset – [in] Destination starting Y offset

  • src – [in] Source memory address

  • count – [in] size in bytes to copy

  • kind – [in] Type of transfer

Returns:

hipSuccess, hipErrorInvalidValue, hipErrorInvalidPitchValue, hipErrorInvalidDevicePointer, hipErrorInvalidMemcpyDirection

hipError_t hipMemcpyFromArray(void *dst, hipArray_const_t srcArray, size_t wOffset, size_t hOffset, size_t count, hipMemcpyKind kind)#

Copies data between host and device.

Parameters:

  • dst – [in] Destination memory address

  • srcArray – [in] Source memory address

  • wOffset – [in] Source starting X offset

  • hOffset – [in] Source starting Y offset

  • count – [in] Size in bytes to copy

  • kind – [in] Type of transfer

Returns:

hipSuccess, hipErrorInvalidValue, hipErrorInvalidPitchValue, hipErrorInvalidDevicePointer, hipErrorInvalidMemcpyDirection
