Using sizeof with a dynamically allocated array
- by robUK
Hello,
gcc 4.4.1 c89
I have the following code snippet:
#include <stdlib.h>
#include <stdio.h>
char *buffer = malloc(10240);
/* Check for memory error */
if(!buffer)
{
fprintf(stderr, "Memory error\n");
return 1;
}
printf("sizeof(buffer) [ %d ]\n", sizeof(buffer));
However, the sizeof(buffer) always prints 4. I know that a char* is only 4 bytes. However, I have allocated the memory for 10kb. So shouldn't the size be 10240? I am wondering am I thinking right here?
Many thanks for any suggestions,
