createDeviceBuffer method

DeviceBuffer? createDeviceBuffer(
  1. StorageMode storageMode,
  2. int sizeInBytes
)

Allocates a new region of GPU-resident memory.

The storageMode must be either StorageMode.hostVisible or StorageMode.devicePrivate, otherwise an exception will be thrown.

Returns null if the DeviceBuffer creation failed.

Implementation

DeviceBuffer? createDeviceBuffer(StorageMode storageMode, int sizeInBytes) {
  if (storageMode == StorageMode.deviceTransient) {
    throw Exception(
        'DeviceBuffers cannot be set to StorageMode.deviceTransient');
  }
  DeviceBuffer result =
      DeviceBuffer._initialize(this, storageMode, sizeInBytes);
  return result.isValid ? result : null;
}
