/// Requires Capability Set 1:
CoopVec<T, N> coopVecLoad<int N, T>(
    ByteAddressBuffer buffer,
    int byteOffset16ByteAligned)
    where T : __BuiltinArithmeticType;

/// Requires Capability Set 1:

## Generic Parameters #### N : int #### T: [\_\_BuiltinArithmeticType](../interfaces/0_builtinarithmetictype-029j/index.html) ## Parameters #### buffer : [ByteAddressBuffer](../types/byteaddressbuffer-04b/index.html) The source buffer to load data from. #### byteOffset16ByteAligned : int = 0 The byte offset from the start of the buffer. Must be 16-byte aligned. #### buffer : [RWByteAddressBuffer](../types/rwbyteaddressbuffer-0126d/index.html) The source buffer to load data from. #### buffer : [StructuredBuffer](../types/structuredbuffer-0a/index.html)\<[T](../types/structuredbuffer-0a/index.html#typeparam-T), [DefaultDataLayout](../types/defaultdatalayout-07b/index.html)\> The source buffer to load data from. #### buffer : [RWStructuredBuffer](../types/rwstructuredbuffer-012c/index.html)\<[T](../types/rwstructuredbuffer-012c/index.html#typeparam-T), [DefaultDataLayout](../types/defaultdatalayout-07b/index.html)\> The source buffer to load data from. #### buffer : [Ptr](../types/ptr-0/index.html)\<[T](../types/ptr-0/index.html#typeparam-T)\> The source buffer to load data from. ## Return value A new cooperative vector containing the loaded values. ## Availability and Requirements ### Capability Set 1 Defined for the following targets: #### hlsl Available in all stages. #### cpp Available in all stages. #### cuda Available in all stages. #### spirv Available in all stages.
