These functions, and their uses are now listed, but a comprehensive list of language keywords can be found in Appendix B. + +### 2.1 - The libtnsl Type Extension + +`tnsl.reflect._type` *must* be defined as a raw struct which contains minimum information for type identification. This information is stored with every static or dynamic struct so that programs can reflect type information. + +`tnsl.reflect._member` *must* be defined as a raw struct which contains minimum information for member variable identification within a type. The information need not be stored with every member variable, but should be stored somewhere such that the `tnsl.reflect._get` method can make use of it. + +`tnsl.reflect._method` *must* be defined as a raw struct which contains minimum information for method identification within a type. The information need not be stored with every member function, but should be stored somewhere such that the `tnsl.reflect._call` method can make use of it. + +`tnsl.reflect._is` *must* be defined as a function taking two parameters of type `tnsl.reflect._type` and returning a single `bool` as output. This function is called when the `is` operator is envoked. + +`tnsl.reflect._get` *must* be defined as a function taking three parameters. The first parameter will be of type `tnsl.reflect._type`, the second parameter will be of type `~void`, and the third parameter will be of type `tnsl.reflect._member`. The function will return a single `~void` as output. + +In the parameters, the first relates to the type of the struct given, or at least how the callee views the struct. The second is a pointer to the struct itself. The third is the requested member to get. The `~void` returned must point to the requested value. + +`tnsl.reflect._call` *must* be defined as a function taking four parameters. The first parameter will be of type `tnsl.reflect._type`, the second parameter will be of type `~void`, the third parameter will be of type `tnsl.reflect._method`, and the fourth parameter will be of type `~void`. The function will return a single `~void` as output. + +In the parameters, the first relates to the type of the struct given, or at least how the callee views the struct. The second is a pointer to the struct itself. The third is the requested method to call. The fourth is a pointer to the parameters for the method. The `~void` returned must point to the return value of the method. + +### 2.2 - Memory allocation and de-allocation + +`tnsl.algo._alloc` *must* be defined as a function taking a single parameter of type `uint` as the number of bytes to allocate and returning a single `~void` as the pointer to the allocated memory. The memory must be allocated from the heap. + +`tnsl.algo._salloc` *should* be defined as a function taking a single parameter of type `uint` as the number of bytes to allocate and returning a single `~void` as the pointer to the allocated memory. The memory must be allocated from the stack. + +`tnsl.algo._dealloc` *must* be defined as a function taking a single parameter of type `~void` as the pointer to a chunk of allocated memory. The function should deallocate the memory. + +### 2.3 - Extra Types Extension + +`tnsl.box._vect` *must* be a raw struct which vector or simd instructions can be preformed on. + +`tnsl.box._string` *must* be a raw struct which stores a string of text. This text may be ASCII or Unicode, but reguardless must be stored as `charp` values internally. + ## Section 3 - Cross calling C ### Credits -- cgit v1.2.3
