Since the C11 standard, the C language offers the _Generic keyword, which acts as a compile-time switch and allows behavior similar to function overloading, which is common in C++.

| // This allocation system is an old implementation I created inspired by the | |
| // system used by DOOM. It employs a freelist-based approach to allocate memory | |
| // in two different arenas. It is capable of allocating, deallocating, | |
| // identifying double frees, and detecting corrupted memory pointers. | |
| // Additionally, it can determine whether the pointer was returned by any of the | |
| // available arenas. | |
| // It is a straightforward implementation and has not undergone extensive | |
| // testing, so there may be potential issues. However, I hope it proves useful | |
| // to you in some way. Feel free to use and modify it as you see fit. | |
