NAME explain_strtoll_or_die - convert a string to a long integer and report errors
SYNOPSIS #include <libexplain/strtoll.h> long long explain_strtoll_or_die(const char *nptr, char **endptr, int base); long long explain_strtoll_on_error(const char *nptr, char **endptr, int base))
DESCRIPTION The explain_strtoll_or_die function is used to call the strtoll(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strtoll(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_strtoll_on_error function is used to call the strtoll(3) system call. On fail‐ ure an explanation will be printed to stderr, obtained from the explain_strtoll(3) func‐ tion, but still returns to the caller. nptr The nptr, exactly as to be passed to the strtoll(3) system call. endptr The endptr, exactly as to be passed to the strtoll(3) system call. base The base, exactly as to be passed to the strtoll(3) system call.
RETURN VALUE The explain_strtoll_or_die function only returns on success, see strtoll(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_strtoll_on_error function always returns the value return by the wrapped str‐ toll(3) system call.
EXAMPLE The explain_strtoll_or_die function is intended to be used in a fashion similar to the following example: long long result = explain_strtoll_or_die(nptr, endptr, base);
