xml_core()

static int xml_core ( char  previous, const char **  current, xml_flags_t  flags, int(*)(void *state, const char *s)  cb, void *  state  )

XML-escape a character

Parameters

	previous	The source character preceding the current one or '\0' if there was no prior character.
[in,out]	current	Pointer to the current position in a source string being escaped. The pointer is updated based on how many characters are consumed.
	flags	Options for configuring behavior.
	cb	User function for emitting escaped data. This is expected to take a caller-defined state type as the first parameter and the string to emit as the second, and then return an opaque value that is passed back to the caller.
	state	Data to pass as the first parameter when calling cb.

Returns

The return value of a call to cb.

Parameters

s	Source string to process.
