# executeCommandsInBuffer:indirectBuffer:indirectBufferOffset:

Encodes an instruction to run commands from an indirect buffer, using another buffer to provide the command range.

## Declaration

```occ
- (void) executeCommandsInBuffer:(id<MTLIndirectCommandBuffer>) indirectCommandbuffer indirectBuffer:(id<MTLBuffer>) indirectRangeBuffer indirectBufferOffset:(NSUInteger) indirectBufferOffset;
```

## Parameters

- `indirectCommandbuffer`: The doc://com.apple.metal/documentation/Metal/MTLIndirectCommandBuffer instance containing the commands to execute.
- `indirectRangeBuffer`: An indirect buffer containing the execution range, laid out in an doc://com.apple.metal/documentation/Metal/MTLIndirectCommandBufferExecutionRange instance. The maximum length of the range is 16384 commands.
- `indirectBufferOffset`: The number of bytes from the start of indirectRangeBuffer containing the execution range to use. Align the offset on a multiple of 4.
