NAME

       explain_strtoull_or_die - convert string to integer and report errors

SYNOPSIS

       #include <libexplain/strtoull.h>
       unsigned long long explain_strtoull_or_die(const char *nptr, char **endptr, int base);
       unsigned long long explain_strtoull_on_error(const char *nptr, char **endptr, int base))

DESCRIPTION

       The  explain_strtoull_or_die  function  is  used  to  call the strtoull(3) system call. On
       failure an explanation will be printed to stderr, obtained  from  the  explain_strtoull(3)
       function, and then the process terminates by calling exit(EXIT_FAILURE).

       The  explain_strtoull_on_error  function  is  used to call the strtoull(3) system call. On
       failure an explanation will be printed to stderr, obtained  from  the  explain_strtoull(3)
       function, but still returns to the caller.

       nptr    The nptr, exactly as to be passed to the strtoull(3) system call.

       endptr  The endptr, exactly as to be passed to the strtoull(3) system call.

       base    The base, exactly as to be passed to the strtoull(3) system call.

RETURN VALUE

       The  explain_strtoull_or_die  function  only  returns on success, see strtoull(3) for more
       information. On failure, prints an explanation and exits, it does not return.

       The explain_strtoull_on_error function always returns the  value  return  by  the  wrapped
       strtoull(3) system call.

EXAMPLE

       The  explain_strtoull_or_die  function  is intended to be used in a fashion similar to the
       following example:
              unsigned long long result = explain_strtoull_or_die(nptr, endptr, base);
