cudaError_t cudaMalloc ( void **  devPtr, size_t  size   ) Allocates size bytes of linear memory on the device and returns in *devPtr a pointer to the allocated memory. The allocated memory is suitably aligned for any kind of variable. The memory is not cleared. cudaMalloc() returns cudaErrorMemoryAllocation in case of failure. Parameters: devPtr  - Pointer to allocated device memory size  - Requested allocation size in bytes Returns: cudaSuccess, cudaErrorMemoryAllocation See also: cudaMallocPitch, cudaFree, cudaMallocArray, cudaFreeArray, cudaMalloc3D, cudaMalloc3DArray, cudaMallocHost (C API), cudaFreeHost, cudaHostAlloc
