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);

SEE ALSO
       strtoull(3)
	       convert a string to an unsigned long integer

       explain_strtoull(3)
	       explain strtoull(3) errors

       exit(2) terminate the calling process
