memcpy
memcpy( Destination, Source, Num );
[Destination]
A MASM-like expression to evaluate which is the address of the destination buffer.
[Source]
A MASM-like expression to evaluate which is the address of the source buffer.
[Num]
A MASM-like expression to evaluate which is the size (length) of the bytes to be copied.
Copies the contents of the source address to the destination buffer.
None
memcpy(fffff806`6de00000 , @rax, 40);
Copies 0x40 bytes from the buffer pointed by the RAX register to the buffer which its address is fffff806`6de00000.
memcpy($buffer, @rsp, 16);
Copies 0x16 bytes from the stack to the buffer allocated by the event buffer.
Please note that the size argument is passed in the HEX format.
Make sure to acquire a spinlock if the destination buffer might be accessed by different cores simultaneously.
This function checks for the validity of both the source and the destination address before performing the copy.
The support for this function is added from v0.2.
