# setBuffers:offsets:withRange: Binds multiple buffers to the buffer argument table at once, allowing compute kernels to access their data on the GPU. ``` - (void) setBuffers:(id const[]) buffers offsets:(const NSUInteger[]) offsets withRange:(NSRange) range; ``` ## Parameters `buffers` The [`MTLBuffer`](/documentation/Metal/MTLBuffer) instances to bind to the buffer argument table. `offsets` An array of offsets, each of which specifies where the data begins, in bytes, from the start of its corresponding buffer. `range` The argument table indices to bind each of the `buffers` to, in the order they appear. ## Discussion> Important: > This method requires that the length of `buffers` and `offsets` are equal to the length of `range`. For buffers binding to an argument using the `device` address space, align the offset to the data type’s size. The maximum size for an offset is `16` bytes. For buffers in the `constant` address space, the minimum alignment depends on the hardware running your app. See the [Metal feature set tables (PDF)](https://developer.apple.com/metal/Metal-Feature-Set-Tables.pdf) for information on each Apple GPU family. Rebinding an already bound buffer causes a Metal error. --- Copyright © 2026 Apple Inc.
