The following example illustrates the use of the execution path recovery feature in HP
WDB:
Sample Program:
$cat execpath.c
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int main()
{
int a = 3, b = 0, c = 4;
if (a)
printf("Value of a greater than 0\n");
if (b)
printf("Value of b greater than 0\n");
if (c)
printf("Value of c greater than 0\n");
printf("All condition checking done\n");
return 0;
}
Sample Debugging Session:
$cc +pathtrace -g execpath.c
$gdb a.out
HP gdb ...
Type "show warranty" for warranty/support.
...
(gdb) b main

(gdb) r
Starting program: a.out
Breakpoint 1, main () at execpath.c:7
7 int a = 3, b = 0, c = 4;
(gdb) n
