Function Documentation

itoa()

char * itoa	(	int	value,
		char *	string,
		int	radix
	)

Convert an int to a null-terminated string.

Parameters

value	Value to convert. Negative values are only signed for radix 10.
string	Buffer to write the result to. Must be large enough for the result.
radix	Base to use, from 2 to 36.

Returns

Pointer to string, or NULL if string is NULL or radix is out of range.

ltoa()

char * ltoa	(	long	value,
		char *	string,
		int	radix
	)

Convert a long to a null-terminated string.

Parameters

value	Value to convert. Negative values are only signed for radix 10.
string	Buffer to write the result to. Must be large enough for the result.
radix	Base to use, from 2 to 36.

Returns

Pointer to string, or NULL if string is NULL or radix is out of range.

ultoa()

char * ultoa	(	unsigned long	value,
		char *	string,
		int	radix
	)

Convert an unsigned long to a null-terminated string.

Parameters

value	Value to convert.
string	Buffer to write the result to. Must be large enough for the result.
radix	Base to use, from 2 to 36.

Returns

Pointer to string, or NULL if string is NULL or radix is out of range.

utoa()

char * utoa	(	unsigned	value,
		char *	string,
		int	radix
	)

Convert an unsigned int to a null-terminated string.

Parameters

value	Value to convert.
string	Buffer to write the result to. Must be large enough for the result.
radix	Base to use, from 2 to 36.

Returns

Pointer to string, or NULL if string is NULL or radix is out of range.
