2.3.23. aocl_mmd_shared_alloc
Shared allocations can migrate between the host and one or more associated device. The same pointer to a shared allocation can be used on the host and the supported device. They have address equivalence.
Syntax
void * aocl_mmd_shared_alloc (int handle, size_t size, size_t alignment, aocl_mmd_mem_properties_t* properties, int* error);
Function Arguments
- handle—Device that needs access to this memory.
- size—The size of the memory region.
- alignment—The alignment (in bytes) of the allocation.
- properties—Specifies additional information about the allocated memory described by a property type name and its corresponding value. Each property type name is immediately followed by the corresponding desired value. The list is terminated with a zero. Supported values are described above. For example, [<property1>, <value1>, <property2>, <value2>, 0]
- error—The error code defined by AOCL_MMD_ERROR*.
- AOCL_MMD_ERROR_SUCCESS—No error occurred.
- AOCL_MMD_ERROR_INVALID_HANDLE—The device handle provided is invalid.
- AOCL_MMD_ERROR_OUT_OF_MEMORY—Ran out of memory.
- AOCL_MMD_ERROR_UNSUPPORTED_ALIGNMENT—The device does not support the provided alignment.
- AOCL_MMD_ERROR_UNSUPPORTED_PROPERTY—The device does not support the provided property.
Return Values
If the aocl_mmd_shared_alloc function executes successfully, the return value is a valid pointer value. Otherwise, the return value is NULL.
