A collection of public domain single-file custom allocators for C/C++.
Copy the desired source file to your project, include it wherever necessary and
add a #define <ALLOCATOR_NAME>_IMPLEMENTATION before including it in exactly
one C/C++ file to create the implementation.
A Stack (Bump) Allocator implementation, maintaining a memory buffer and the current allocation marker.
Allocation markers can be used to free allocator up to some point, instead of clearing the entire stack. In particular, when allocating elements of a single type, this becomes a generic stack implementation.
There are typed macros for functions that expect size values, to help in readability.
There are also FOREACH macros for iterating stack in allocation order or reversed allocation order,
assuming that all values are of the same type.
A Double Ended Stack (Bump) Allocator implementation, maintaining a memory buffer and current allocation markers for both ends.
Allocation markers can be used to free allocator up to some point, instead of clearing the entire stack on either end. In particular, when allocating elements of a single type, this becomes a generic double ended stack implementation, possibly with different types for each side.
There are typed macros for functions that expect size values, to help in readability.
There are also FOREACH macros for iterating stack in allocation order or reversed allocation order,
assuming that all values are of the same type.
