Data Structures
struct	ticktock_t
Functions
muse_int	muse_hash_data (const unsigned char *start, const unsigned char *end, muse_int initial)
	Creates a simple hash of the given data.
muse_int	muse_hash_text (const muse_char *start, const muse_char *end, muse_int initial)
	A hash similar to muse_hash_data, but tailored for text.
muse_int	muse_hash (muse_cell obj)
	Hashes a given cell reference.
void *	muse_tick ()
	Used for performance timing.
muse_int	muse_tock (void *arg)
	When passed the timing handle returned by muse_tick(), it returns the time elapsed between the muse_tick() call and this muse_tock() call in microseconds.
void	muse_sleep (muse_int time_us)
	Sleeps the muse process for the given time in microseconds.
FILE *	muse_fopen (const muse_char *filename, const muse_char *options)
	A wrapper to the common fopen function so that we can call _wfopen if available, or the narrow version if the wide version isn't available.
int	muse_unicode_to_utf8 (char *out, int out_maxlen, const muse_char *win, int win_len)
	Converts the given double-byte unicode string to multibyte UTF8 string.
int	muse_utf8_to_unicode (muse_char *wout, int wout_maxlen, const char *in, int in_len)
	Converts the given UTF8 string to double-byte unicode string.
int	muse_utf8_size (const muse_char *wstr, int length)
	Returns an estimate of the number of bytes (conservative upper bound) that might be needed to represent the given number of unicode characters using UTF8 encoding.
int	muse_unicode_size (const char *utf8, int nbytes)
	Returns an estimate (conservative upper bound) of the number of bytes that will be required to store the converted unicode version of the given utf8 string.
void	muse_assert_failed (const char *file, int line, const char *condtext)
	Prints out an muse_assertion failure message in debug builds.
const muse_char *	muse_typename (muse_cell thing)
	Returns a non-mutable string describing the type of the thing passed as the parameter.
static void	muse_exception (muse_cell args)
static int	muse_sprintf_object (muse_char *buffer, int maxlen, muse_cell thing)
static int	muse_sprintf_list (muse_char *buffer, int maxlen, muse_cell list)

static int	muse_vsprintf (muse_char *buffer, int maxlen, const muse_char *format, va_list *argv)
int	muse_sprintf (muse_char *buffer, int maxlen, const muse_char *format,...)
	Formats a string consisting of the given format string with the other argument objects inserted at specified positions.
void	muse_message (const muse_char *context, const muse_char *message,...)
	Displays a message string formatted according to the given message string with format codes.
static muse_boolean	muse_test (const muse_char *context, const muse_char *spec, va_list *argv)
static muse_boolean	muse_test_one (const muse_char *context, muse_boolean force, muse_boolean invert, muse_cell symbol, muse_cell value, const muse_char *spec, va_list *argv, muse_char *failure_descr)
static int	levenshtein_distance (const muse_char *s1, const muse_char *s2)
muse_boolean	muse_expect (const muse_char *context, const muse_char *spec,...)
	Checks whether a set of expectations are satisfied by some values.
muse_cell	muse_similar_symbol (muse_cell symbol, int *outDistance)
	Sometimes, it is useful to know whether another symbol that's very similar in textual representation from a known symbol.
muse_cell	muse_symbol_with_value (muse_cell value)
	Searches the symbol table to find a symbol whose current value is the given cell.
static muse_boolean	muse_test_limit (const muse_char *context, muse_boolean force, muse_cell symbol, muse_cell value, muse_float limit, int comparison, int invert, const muse_char *descr, muse_char *failure_descr)
