Function Documentation

pm_memchr()

void* pm_memchr	(	const void *	source,
		int	character,
		size_t	number,
		bool	encoding_changed,
		const pm_encoding_t *	encoding
	)

We need to roll our own memchr to handle cases where the encoding changes and we need to search for a character in a buffer that could be the trailing byte of a multibyte character.

Parameters

source	The source string.
character	The character to search for.
number	The maximum number of bytes to search.
encoding_changed	Whether the encoding changed.
encoding	A pointer to the encoding.
