explain_strtoll_or_die(3) Library Functions Manual explain_strtoll_or_die(3) 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) sys- tem 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 failure an explanation will be printed to stderr, ob- tained from the explain_strtoll(3) function, 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 str- toll(3) for more information. On failure, prints an explanation and ex- its, it does not return. The explain_strtoll_on_error function always returns the value return by the wrapped strtoll(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); SEE ALSO strtoll(3) convert a string to a long integer explain_strtoll(3) explain strtoll(3) errors exit(2) terminate the calling process COPYRIGHT libexplain version 1.3 Copyright (C) 2009 Peter Miller explain_strtoll_or_die(3)
