How can I access heap memory next to using malloc?

Question

Is there a way that you can assign memory from a heap without calling malloc? Could this call be affective for him?

void* loc = (void*) &heap[end_of_heap];

Answer 1

No. The C language itself does not provide such functions. If you do not care what Unix systems comply with outdated features of the old version of the Unix standard (SUSv2 or earlier, if I remember correctly), the functions brkand sbrkprovide this function. But you really shouldn't use it unless you write very low-level code that you never need to port.
