This C tutorial explains how to use the #ifdef preprocessor directive in the C language. Description In the C Programming Language, the #ifdef directive allows for conditional compilation. The preprocessor dete
Nesting of multi-line comments are not allowed in C programming language. So instead of commenting the code we could make use of #ifdef directive. 2. To write portable code: For example, we could write code both for iOS and non-iOS devices. Using #ifdef we could check the device OS ...
ifdef __linux__ #ifdef __linux__ is a preprocessor directive used in C and C++ programming languages to check if the code is being compiled on a Linux operating system. This directive allows developers to write platform-specific code that will only be included in the final executable when i...
These directives check only for the presence or absence of identifiers defined using the #define directive, not for identifiers declared in the C or C++ source code. These directives are provided only for compatibility with previous versions of the language. The use of the defined operator with ...

The issue is that in order for trimming to be safe, the compiler needs to be extremely accurate when trimming out code that should never be executed. When reflection and dynamic programming are used instead, these assumptions can end up being inaccurate, and bad things can ...
In the programming language C every non-zero value is taken to mean true when interpreted as a boolean. If we wanted to have these semantics for the Makefile-based builds, a proper check would look like this in pseudo code: if not defined NO_FOO or NO_FOO=0; then enable foo; fi if...
[]argsdefinition. That is the parameter definition that contains all the arguments that are passed down to our executable during the initialization of our process. Unlike C and C++, the name of the program is not treated as the first command-line argument in the args array. If you want ...
Here’s a quick photo of when I was remoting in from my truck, using my Surface Pro 8. One reason I like to use my Surface for this, is that I can charge it using USB-C in my truck or the field battery when I’m out imaging. ...
