Release memory from the Mosel execution stack.

This function restores the level of the Mosel execution stack to the specified address. This reference address is a pointer returned by a preceding call to stackalloc and all the memory allocated by any following invocation of the memory allocator are also released ( i.e. if several memory blocks have been allocated on the stack only the first one must be released with this function independently of the relative order of the corresponding addresses).
