NxLib API > Commands

The item /Execute at the root tree level provides a flexible interface for the execution of predefined library functions.

Note: You might look at the HowTo section to see some C++ code fragments explaining how to perform basic tasks.

To execute a command you might first need to write parameters into the /Execute/Parameters node. Then you can start the execution by writing the command name into the /Execute/Command node. After the command has been executed, the Function subnode will be reset to Null. You can thus wait for the execution to complete by waiting for Command node to become Null again. If the execution was not successful, the it will leave an ErrorSymbol and ErrorText node under the Result subnode. Some commands might also return result values, these will be placed under the Result node. The exact format of the returned result is laid out in the description of the corresponding command.
