explain_strtold_or_die(3)  Library Functions Manual  explain_strtold_or_die(3)

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) sys-
       tem 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, ob-
       tained 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 str-
       told(3) for more	information. On	failure, prints	an explanation and ex-
       its, 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);
