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.

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);
