void pointer as function argument in C programming
- The void pointer is also known as generic pointer, this pointer can be pointed at objects of any type.
- A void pointer is declared like a normal pointer, using the void keyword as the pointer's type:
void *ptr; // ptr is a void pointer.
Sample Code
#include <stdio.h>
void printString(void *ptr);
int main()
{
char *str="hi there";
printString(str);
return 0;
}
void printString(void *ptr)
{
printf("str: %s\n",ptr);
}
Output
str: hi there
