c print stack pointer
How to set a stack pointer in C?
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.
What is a stack pointer?
The program counter would be better called the next/current instruction pointer.
It is where the processor is up to in the code.
The stack pointer refers to data, not code.
The stack is a major memory area where data is kept and your local variables are created and deallocated (low-cost automatic memory management).How to print a stack 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.
