Function scratchstack_wrapper_aws_c_common::aws_mem_realloc

pub unsafe extern "C" fn aws_mem_realloc(
    allocator: *mut aws_allocator,
    ptr: *mut *mut c_void,
    oldsize: usize,
    newsize: usize
) -> c_int

Attempts to adjust the size of the pointed-to memory buffer from oldsize to newsize. The pointer (*ptr) may be changed if the memory needs to be reallocated.

In versions v0.6.8 and prior, this function was allowed to return NULL. In later versions, if allocator->mem_realloc() returns NULL, this function will assert and exit. To handle conditions where OOM is not a fatal error, allocator->mem_realloc() is responsible for finding/reclaiming/running a GC etc…before returning.
