NAME
       explain_strtoll_or_die - convert a string to a long integer and report errors

SYNOPSIS
       #include <libexplain/strtoll.h>
       long long explain_strtoll_or_die(const char *nptr, char **endptr, int base);
       long long explain_strtoll_on_error(const char *nptr, char **endptr, int base))

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

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

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

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

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

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

       The explain_strtoll_on_error function always returns the value return by the wrapped strtoll(3) system call.

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

SEE ALSO
       strtoll(3)
	       convert a string to a long integer

       explain_strtoll(3)
	       explain strtoll(3) errors

       exit(2) terminate the calling process
