    push a constant #index from a constant pool (String, int, float, Class, java.lang.invoke.MethodType, java.lang.invoke.MethodHandle, or a dynamically-computed constant) onto the stack (wide index is constructed as indexbyte1 << 8 | indexbyte2) ldc2_w 14 0001 0100 2: indexbyte1, indexbyte2 → value

  3. Null pointer - Wikipedia

    en.wikipedia.org/wiki/Null_pointer

    In some programming language environments (at least one proprietary Lisp implementation, for example), [citation needed] the value used as the null pointer (called nil in Lisp) may actually be a pointer to a block of internal data useful to the implementation (but not explicitly reachable from user programs), thus allowing the same register to be used as a useful constant and a quick way of ...

  4. Dangling pointer - Wikipedia

    Dangling pointer. Dangling pointers and wild pointers in computer programming are pointers that do not point to a valid object of the appropriate type. These are special cases of memory safety violations.

  5. Function pointer - Wikipedia

    en.wikipedia.org/wiki/Function_pointer

    The next program uses a function pointer to invoke one of two functions (sin or cos) indirectly from another function (compute_sum, computing an approximation of the function's Riemann integration). The program operates by having function main call function compute_sum twice, passing it a pointer to the library function sin the first time, and ...

  6. Platform Invocation Services - Wikipedia

    en.wikipedia.org/wiki/Platform_Invocation_Services

    Instead of using standard .NET parameter types in P/Invoke method definitions (char[], string, etc.) it uses these interface classes in the P/Invoke function calls. For instance, if we consider the above example code, PInvoker would produce a .NET P/Invoke function accepting a .NET interface class wrapping the native char * pointer.

  7. x86 calling conventions - Wikipedia

    en.wikipedia.org/wiki/X86_calling_conventions

    In the context of the language C, function arguments are pushed on the stack in the right-to-left (RTL) order, i.e. the last argument is pushed first. Consider the following C source code snippet: int callee ( int , int , int ); int caller ( void ) { return callee ( 1 , 2 , 3 ) + 5 ; }

    The null coalescing operator is a binary operator that is part of the syntax for a basic conditional expression in several programming languages, such as (in alphabetical order): C# [1] since version 2.0, [2] Dart [3] since version 1.12.0, [4] PHP since version 7.0.0, [5] Perl since version 5.10 as logical defined-or, [6] PowerShell since 7.0.0, [7] and Swift [8] as nil-coalescing operator.
