Question

I need to keep a list to simulate memory management. The program assigns a certain number of bytes to a certain process – the processes are bogus, since there are no actual processes, but basically I am thinking all I need is a list of integers.

Currently I have:

#define ALLOCSIZE
#define *int[ALLOCSIZE]

I think that is right? My C class has a method:

initialize_memory(int size)
{

}

I don’t want to use anything fancy, all I want is just a list of integers.

Remove the DEFINES, you don’t need them here.

Use calloc:

int* memory = (int*)calloc(bytes, sizeof(int));

You will need to free this memory when you’re done with it:

free(memory);
