Function JxlDecoderGetFrameName 

pub unsafe extern "C-unwind" fn JxlDecoderGetFrameName(
    dec: *const JxlDecoder,
    name: *mut c_char,
    size: usize,
) -> JxlDecoderStatus

Outputs name for the current frame. The buffer for name must have at least name_length + 1 bytes allocated, gotten from the associated JxlFrameHeader.

Parameters

• dec: decoder object
• name: buffer to copy the name into
• size: size of the name buffer in bytes, including zero termination character, so this must be at least JxlFrameHeader::name_length + 1.

Returns

• JxlDecoderStatus::Success if the value is available
• JxlDecoderStatus::NeedMoreInput if not yet available
• JxlDecoderStatus::Error in case of other error conditions.
