heap |
The sound heap handle. |
size |
The memory size to be allocated. |
callback |
The callback function called when the memory block is de-allocated. |
data1, data2 |
The user data for the argument of the callback function. |
Returns the starting address of the allocated memory block. Returns a NULL if the allocation fails.
Allocates memory from the sound heap.
A management region is needed in each memory block. In actuality, a space slightly larger than the memory size size to be allocated is necessary. The function will fail if there is not enough space.
The callback function callback is called when the memory block is de-allocated via the NNS_SndHeapClear function or the NNS_SndHeapLoadState function. The memory block starting address mem, the memory block size size, and the user data data1 and data2 are passed to the argument of the callback function. Enter a NULL into callback when the callback function is not needed.
