Function Documentation

SkStrAppendS32()

char* SkStrAppendS32	(	char	buffer[],
		int32_t
	)

SkStrAppendS64()

char* SkStrAppendS64	(	char	buffer[],
		int64_t	,
		int	minDigits
	)

SkStrAppendScalar()

char* SkStrAppendScalar	(	char	buffer[],
		SkScalar
	)

Write the scalar in decimal format into buffer, and return a pointer to the next char after the last one written.

Note: a terminating 0 is not written into buffer, which must be at least kSkStrAppendScalar_MaxSize. Thus if the caller wants to add a 0 at the end, buffer must be at least kSkStrAppendScalar_MaxSize + 1 bytes large.

SkStrAppendU32()

char* SkStrAppendU32	(	char	buffer[],
		uint32_t
	)

SkStrAppendU64()

char* SkStrAppendU64	(	char	buffer[],
		uint64_t	,
		int	minDigits
	)

kSkStrAppendS32_MaxSize

constexpr int kSkStrAppendS32_MaxSize = kSkStrAppendU32_MaxSize + 1

staticconstexpr

kSkStrAppendS64_MaxSize

constexpr int kSkStrAppendS64_MaxSize = kSkStrAppendU64_MaxSize + 1

staticconstexpr

kSkStrAppendScalar_MaxSize

constexpr int kSkStrAppendScalar_MaxSize = 15

staticconstexpr

Floats have at most 8 significant digits, so we limit our g to that.

However, the total string could be 15 characters: -1.2345678e-005

In theory we should only expect up to 2 digits for the exponent, but on some platforms we have seen 3 (as in the example above).

kSkStrAppendU32_MaxSize

kSkStrAppendU64_MaxSize
