inlinestatic

Queries if the passed pointer points to a newline character.

What is a newline and what is not depends on the passed encoding.

Parameters

[in]	p	Pointer to a possibly-middle of a character.
[in]	end	End of the string.
[in]	enc	Encoding.

Return values

false	It isn't.
true	It is.

		rb_encoding *	enc
	)

inlinestatic

Identical to rb_isalnum(), except it additionally takes an encoding.

Parameters

[in]	c	A code point.
[in]	enc	An encoding.

	)

inlinestatic

Identical to rb_isascii(), except it additionally takes an encoding.

Parameters

[in]	c	A code point.
[in]	enc	An encoding.

Return values

false	`c` is out of range of ASCII character set in `enc`.
