Hi,

I know that atoi converts const char *string to a integer with 32-bits... but to uint64_t this do not work...

You can use std::istringstream.

std::istringstream iss(str);
iss >> t;

or in one line

std::istringstream(str) >> t;

Hi,

I find this, works also:

unsigned long strtoul(const char *nptr, char **endptr, int base);

and works in C and C++.

@Peter87:thanks...
