+# `bitmap_init_from_buffer(buffer, size)` - function (bitmap_T)
+Creates a bitmap object from a given buffer and size
+
+# `bitmap_init(size)` - function (bitmap_T)
+Allocates memory to hold a bitmap in the given size and returns a [bitmap_T](https://nerdcult.net/projects/noxos/docs/codebase/utils/bitmap.h/#bitmap_t---struct) with that buffer and size.
+
+# `bitmap_destruct(bitmap*)` - function (void)
+Frees the memory of the given bitmap created with [bitmap_init](https://nerdcult.net/projects/noxos/docs/codebase/utils/bitmap.h/#bitmap_initsize---function-bitmap_t).
+
+# `bitmap_set(bitmap*, index, value)` - function (bool)
+Sets the bit at the given index in the given bitmap to the given boolean value.
+Returns **false**, if the index is out of the bitmaps size bounds.
+Returns **true**, if the operation was successful.
+
+# `bitmap_get(bitmap*, index)` - function (bool)
