Function names are mangled by default in Rust. However, this can be disabled by the #[no_mangle] function attribute. This attribute can be used to export functions to C, C++, or Objective-C. [9] Further, along with the #[start] function attribute or the #[no_main] crate attribute, it allows the user to define a C-style entry point for the ...
In Go, the convention is to use MixedCaps or mixedCaps rather than underscores to write multiword names. When referring to structs or functions, the first letter specifies the visibility for external packages. Making the first letter uppercase exports that piece of code, while lowercase makes it only usable within the current scope. [24]
The following programming languages use snake case by convention: ABAP [8] Ada, with initial letters also capitalized [9] C++, Boost [10] C, for some type names in the standard library, but not for function names. Eiffel, for class and feature names [11] Elixir, for atom, variable, and function names [12] Erlang, for function names [13]
This is most often done by using a prefix, often one or more underscores. C and C++ are notable in this respect: C99 reserves identifiers that start with two underscores or an underscore followed by an uppercase letter, and further reserves identifiers that start with a single underscore (in the ordinary and tag spaces) for use in file scope ...
Also (as with structs), the C++ enum keyword is combined with a typedef, so that instead of naming the type enum name, simply name it name. This can be simulated in C using a typedef: typedef enum {Value1, Value2} name; C++11 also provides a second kind of enumeration, called a scoped enumeration. These are type-safe: the enumerators are not ...
In fact, the use of a single underscore for this became so common that C compilers had to standardize on a double leading underscore (for instance __DATE__) for actual built-in variables to avoid conflicts with the ones in header files. PHP "reserves all function names starting with __ as magical." [10]

A function signature consists of the function prototype. It specifies the general information about a function like the name, scope and parameters. Many programming languages use name mangling in order to pass along more semantic information from the compilers to the linkers. In addition to mangling, there is an excess of information in a ...
