initblk |
Set each location in a block of memory to a given value. |
The stack transitional behavior, in sequential order, is:
A starting address is pushed onto the stack.
An initialization value is pushed onto the stack.
The number of bytes to initialize is pushed onto the stack.
The number of bytes, the initialization value, and the starting address are popped from the stack, and the initialization is performed as per their values.
The initblk instruction sets the number (unsigned int32) of bytes starting at the specified address (of type native int, &, or *) to the initialization value (of type unsigned int8). initblk assumes that the starting address is aligned to the natural size of the machine.
The operation of the initblk instructions can be altered by an immediately preceding Volatile or Unaligned prefix instruction.
NullReferenceException may be thrown if an invalid address is detected.
The following Emit method overload can use the initblk opcode:
- ILGenerator.Emit(OpCode)
