Function encoding_c::encoding_ascii_valid_up_to
[−]
[src]
#[no_mangle]pub unsafe extern fn encoding_ascii_valid_up_to(buffer: *const u8,
buffer_len: usize)
-> usize
Validates ASCII.
Returns the index of the first byte that makes the input malformed as
ASCII or buffer_len
if buffer
is entirely valid.
Undefined behavior
UB ensues if buffer
and buffer_len
don't designate a valid memory block.
