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) 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 fail‐ ure an explanation will be printed to stderr, obtained from the explain_strtold(3) func‐ tion, 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 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 str‐ told(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);
