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);
