Function libjxl_sys::JxlDecoderGetFrameName

pub unsafe extern "C" 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.

@param dec decoder object @param name buffer to copy the name into @param size size of the name buffer in bytes, including zero termination character, so this must be at least JxlFrameHeader.name_length + 1. @return @ref JXL_DEC_SUCCESS if the value is available, @ref JXL_DEC_NEED_MORE_INPUT if not yet available, @ref JXL_DEC_ERROR in case of other error conditions.
