ll2str()

MYSQL_STRINGS_EXPORT char * ll2str	(	int64_t	val,
		char *	dst,
		int	radix,
		bool	upcase
	)

Converts a 64-bit integer value to its character form and moves it to the destination buffer followed by a terminating NUL.

If radix is -2..-36, val is taken to be SIGNED, if radix is 2..36, val is taken to be UNSIGNED. That is, val is signed if and only if radix is. All other radixes are treated as bad and nothing will be changed in this case.

For conversion to decimal representation (radix is -10 or 10) one should use the optimized longlong10_to_str() function instead.

Parameters

val	the value to convert
dst	the buffer where the string representation should be stored
radix	radix of scale of notation
upcase	true if we should use upper-case digits

Returns

pointer to the ending NUL character, or nullptr if radix is bad

llstr()

static char * llstr ( long long  value, char *  buff  )

longlong10_to_str()

MYSQL_STRINGS_EXPORT char * longlong10_to_str	(	int64_t	val,
		char *	dst,
		int	radix
	)

Converts a 64-bit integer to its string representation in decimal notation.

It is optimized for the normal case of radix 10/-10. It takes only the sign of radix parameter into account and not its absolute value.

Parameters

val	the value to convert
dst	the buffer where the string representation should be stored
radix	10 if val is unsigned, -10 if val is signed

Returns

pointer to the ending NUL character
