This is wrapper function to memcpy function. This function takes size of two memory regions to make sure not read from or write to out of bound memory region. Since 0 is valid address, Src and Dest parameter are not checked for NULL.
Copies Len bytes from source memory to destination memory, allows overlapped memory between source and destination
Prototype
s32 Xil_SMemCpy(void *Dest, const u32 DestSize, const void *Src, const u32 SrcSize, const u32 CopyLen);Parameters
The following table lists the Xil_SMemCpy function arguments.
| Type | Member | Description |
|---|---|---|
| void * | Dest | - Pointer to destination memory |
| const u32 | DestSize | - Memory available at destination |
| const void * | Src | - Pointer to source memory |
| const u32 | SrcSize | - Maximum data that can be copied from source |
| const u32 | CopyLen | - Number of bytes to be copied |
