explain_strtof_or_die(3)   Library Functions Manual   explain_strtof_or_die(3)

NAME
       explain_strtof_or_die - convert string to number	and report errors

SYNOPSIS
       #include	<libexplain/strtof.h>
       float explain_strtof_or_die(const char *nptr, char **endptr);
       float explain_strtof_on_error(const char	*nptr, char **endptr))

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

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

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

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

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

       The explain_strtof_on_error function always returns the value return by
       the wrapped strtof(3) system call.

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

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

       explain_strtof(3)
	       explain strtof(3) errors
