       These  functions are just like strtol(3) and strtoul(3), except that they return a value of type intmax_t
       and uintmax_t, respectively.

       strtoimax, strtoumax - convert string to integer

       On success, the converted value is returned.  If nothing was found to  convert,  zero  is  returned.   On
       overflow or underflow INTMAX_MAX or INTMAX_MIN or UINTMAX_MAX is returned, and errno is set to ERANGE.
