GLibutf8_validate_len

gboolean
g_utf8_validate_len (
  const gchar* str,
  gsize max_len,
  const gchar** end
)

Validates UTF-8 encoded text.

As with g_utf8_validate(), but max_len must be set, and hence this function will always return FALSE if any of the bytes of str are nul.

Available since:

2.60

`str`	An array of `guint8`
	A pointer to character data.
	The length of the array is specified in the `max_len` argument.
	The data is owned by the caller of the function.
`max_len`	`gsize`
	Max bytes to validate.
`end`	`const gchar**`
	Return location for end of valid data.
	The argument will be set by the function.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
	The value is a NUL terminated UTF-8 string.
