# executeCommandsInBuffer:indirectBuffer:indirectBufferOffset: Encodes an instruction to run commands from an indirect buffer, using another buffer to provide the command range. ``` - (void) executeCommandsInBuffer:(id) indirectCommandbuffer indirectBuffer:(id) indirectRangeBuffer indirectBufferOffset:(NSUInteger) indirectBufferOffset; ``` ## Parameters `indirectCommandbuffer` The [`MTLIndirectCommandBuffer`](/documentation/Metal/MTLIndirectCommandBuffer) instance containing the commands to execute. `indirectRangeBuffer` An indirect buffer containing the execution range, laid out in an [`MTLIndirectCommandBufferExecutionRange`](/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`. --- Copyright © 2026 Apple Inc.
