Please look at the snipped of code:

#include <stdio.h>

main () {

  char* buf = NULL;

  buf = (char*)malloc(100);
  strcpy(buf, "Klaus Berndl");
  printf("\n%s\n", buf);

/* line 10 */  buf = (char*)realloc(buf, strlen(buf)+1);  /* line 10 */

  if (buf)
    printf("\n%s\n", buf);
  else
    printf("\nshit!\n");
}

My questions are now: How much memory is allocated for 'buf' after
executing line 10?! Does realloc 'freeing' the storage behind byte 13?
Or are still 100 bytes allocated for buf?

I`m working with Solaris 2.4 and SUNOS 4.1.3C


Many thanks in advance!


Ciao,
