Hello Akshatha,
If you don't find a better solution, you could have an uint64_t
parameter in your function and pass a casted pointer as argument.
Inside the function it can be treated as a pointer. Something like
this:
// $ gcc -Wextra -g -O0 pointer.c -o pointer// $ ./pointer
#include <stdio.h>#include <stdint.h>
void foo(uint64_t p){ const size_t max_size = 32; char
*str = strndup((char *)p, max_size); printf("(%s, %s) p:
0x%llx\n", __FILE__, __func__, p); printf("string: %s\n", (char
*)p); printf("string: %s\n", str); free(str);}
int main(int argc, const char *argv[]){ uint8_t array[64] =
"Greetings!"; void *p = array; printf("(%s, %s) p: %p\n",
__FILE__, __func__, p); foo((uint64_t)p); return 0;}
Hope it helps.
Regards,Éder
