NAME

       explain_strtold_or_die - convert string to number and report errors

SYNOPSIS

       #include <libexplain/strtold.h>
       long double explain_strtold_or_die(const char *nptr, char **endptr);
       long double explain_strtold_on_error(const char *nptr, char **endptr))

DESCRIPTION

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

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

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

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

RETURN VALUE

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

       The explain_strtold_on_error function always returns  the  value  return  by  the  wrapped
       strtold(3) system call.

EXAMPLE

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