It means that all entities in the namespace std will be "lifted" into the global namespace, meaning you won't have to use the std:: for them. If you don't type it, then you can still use them albeit with the pr
* * This function follows the WHATWG forgiving-base64 format, which means that it * will ignore any ASCII spaces in the input. You may provide a padded input * (with one or two equal signs at the end) or an unpadded input (without any * equal signs at the end). * * See https:...
-m: Memory mapped; used for the C270 webcam -u: Userspace pointers -r: Direct read/write Another important argument is - f. If this argument is not set, the current camera settings are used to capture the video. This means you can change them using the v4l2-ctl tool, as explained...
Header units need to work like a PCH where they record macros and pragma state, which includes#pramga once. This means that the IFC needs to record symbolic links and their “unwrapped” files so that the compiler can properly enforce#pragma once. After this work was done, many more scenar...

Additionally, the runtime specifies anaccess_typeofaccess_type_autofor the default accelerator. This means that the default accelerator uses shared memory if it's supported and if its performance characteristics (bandwidth and latency) are known to be the same as dedicated (non-shared) memory. ...
