>Description:
I am unable to sscanf correctly 2 integers from a string. A Sample
program that recreates the problem is shown below. This is a problem
in both libc and libc_r.
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
main()
{
char *tmp = "999 12346";
char *ptr;
unsigned short x;
unsigned short y;
unsigned short z;
unsigned int a;
int result;
result = sscanf ( tmp, "%d %d", &x, &y );
z = strtol ( tmp, &ptr, 0 );
a = atoi ( tmp );
(void)fprintf ( stderr, "x(%d)y(%d)z(%d)a(%d)\n", x, y, z, a );
exit ( 0 );
}
>How-To-Repeat:
Run the above program.
