Function Documentation

double explain_strtod_or_die	(	const char *	nptr,
		char **	endptr
	)

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).

Parameters:

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.

Returns:

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

Example:

This function is intended to be used in a fashion similar to the following example:

 double result = explain_strtod_or_die(nptr, endptr);
