A stack pointer is a small register that stores the memory address of the last data element added to the stack or, in some cases, the first available address in the stack.
How to set a stack pointer in C?
To set up the stack pointers, enter each mode with interrupts disabled, and assign the appropriate value to the stack pointer.
The stack pointer value set up in the reset handler is automatically passed as a parameter to __user_initial_stackheap() by C library initialization code.
How do you use pointers in stack?
The Stack Pointer (SP) register is used to indicate the location of the last item put onto the stack.
When you PUT something ONTO the stack (PUSH onto the stack), the SP is decremented before the item is placed on the stack.
How to read the stack in C?
In C, you can access a stack memory data structure using the following steps:
1Declare a pointer to the top of the stack.2) Allocate memory for a new element using malloc() or calloc() .
3) Assign the new element's value.
4) Update the top pointer to point to the new element.
