Function ddwaf_allocator_free 

pub unsafe extern "C" fn ddwaf_allocator_free(
    alloc: ddwaf_allocator,
    p: *mut c_void,
    bytes: usize,
    alignment: usize,
)

Releases a block of memory previously obtained via ddwaf_allocator_alloc from the same allocator.

Requirements and safety:

• p must point to memory returned by ddwaf_allocator_alloc using alloc.
• bytes and alignment must match the values used for the allocation.
• After this call, the memory referenced by p must no longer be accessed.
• Do not mix allocators; freeing with a different allocator is undefined.
• Thread-safety depends on the allocator type; see the corresponding allocator init function for details.

@param alloc Allocator used for the original allocation. (nonnull) @param p Pointer to the memory to free. (nonnull) @param bytes Size in bytes of the original allocation. @param alignment Alignment in bytes of the original allocation.
