explain_strtod_or_die(3)   Library Functions Manual   explain_strtod_or_die(3)

NAME
       explain_strtod_or_die - convert string to number	and report errors

SYNOPSIS
       #include	<libexplain/strtod.h>
       double explain_strtod_or_die(const char *nptr, char **endptr);
       double explain_strtod_on_error(const char *nptr,	char **endptr))

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

       The explain_strtod_on_error function is used to call the	strtod(3) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_strtod(3) function, but	still returns to the caller.

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

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

RETURN VALUE
       The  explain_strtod_or_die  function  only returns on success, see str-
       tod(3) for more information. On failure,	prints an explanation and  ex-
       its, it does not	return.

       The explain_strtod_on_error function always returns the value return by
       the wrapped strtod(3) system call.

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

SEE ALSO
       strtod(3)
	       convert ASCII string to floating-point number

       explain_strtod(3)
	       explain strtod(3) errors
