As I mentioned earlier, it is not appropriate to use “null” to get the global HMD_Test_Play_Streaming_url. “null” is typically used to indicate the absence of a value or a variable that has not been initialized.
If you are looking to access the value of the global HMD_Test_Play_Streaming_url variable, you should do so by referencing the variable directly in your code. The exact method for accessing the global variable will depend on the programming language or framework you are using.
For example, in JavaScript, you can access a global variable by simply referring to it by name:
codelet url = HMD_Test_Play_Streaming_url;
In other programming languages, you may need to use a specific syntax or method to access global variables. For instance, in C++, you can access global variables declared in another file by using the extern keyword:
c++Copy codeextern const char* HMD_Test_Play_Streaming_url;
In general, it is important to use appropriate syntax and methods for accessing global variables to ensure that your code runs smoothly and as intended. Using “null” to access global variables is not a best practice and can lead to errors and unexpected behavior.
