Hi,
I must miss something...
Looking at these prototypes
unsigned long simple_strtoul(const char *cp, char **endp,unsigned int base)
unsigned long long memparse (char *ptr, char **retptr)
I'm really wondering why not all parameters are not all 'const'. None
of these functions modify any pointer containts. And simple_strtoul()
ends up doing sometghing like:
if (endp)
*endp = (char *)cp;
Could anyone shed some light ?
The C standard behaves like that, too, mostly because C doesn't have a
way to say "X is const iff Y is const" (unlike C++, btw.)
