How to read/write type values from "raw" memory in C?

Question

How do I make something like this work?

void *memory = malloc(1000);  //allocate a pool of memory
*(memory+10) = 1;  //set an integer value at byte 10
int i = *(memory+10);  //read an integer value from the 10th byte

Answer 1

Easy example: treat the memory as an array of unsigned char

void *memory = malloc(1000);  //allocate a pool of memory
uint8_t *ptr = memory+10;  
*ptr = 1 //set an integer value at byte 10
uint8_t i = *ptr;  //read an integer value from the 10th byte

You can use integers too, but then you must pay attention about the amount of bytes you are setting at once.
