> (atio will not work for hex values)
The atoi function is actually pretty brain-dead, so if you do not know
for certain that your numeric base is decimal, you should use strtol
instead, since it can be passed a base.
Also, if the given base is zero it makes a fairly convincing stab at
guessing the correct base.
I think the man pages actually say this, now I think of it...
Attached example:
#include <stdlib.h>
#include <stdio.h>
int main(void) {
char *txt = "0x0000AA55";
int v;
puts(txt);
v = atoi(txt);
printf("v is : %d (atoi is explicitly base 10)\n", v);
v = (int)strtol(txt, 0, 0);
printf("v is : %d or 0x%08X (strtol handles number base OK)\n",
v, v);
return 0;
}
