A garbage collector in C, which simulate the behavior of the stack inside the heap.

Heap Stack

This project is about creating a stack on the heap based on the attributes of GCC, cleanup, constructor, destructor. This stack is used to automatically wipe memory allocated on the heap.

Usage:

Use the library:

You need to link your library to your binary by running somthing like this:

$ gcc -L<library_location> <CFLAGS> [...] -lheap-stack

Example:

int main(void)
{
    stack_scope;
    int *array = stack_malloc(10 * sizeof(int));

    /* Any other thing you need to do */
    return 0;
} /* array is freed */

Compilation:

All:

This compile test bin example and the shared library.

$ make all

Library:

$ make heap-stack.so

Test Bin:

$ make heap_stack

Debug:

$ make debug <target>

Asan:

$ make asan <target>
