nk::runtime::fscanf
void fscanf(::nk::Engine &engine, Span< const Value > args, size_t nargout, Span< Value > outs)
Reads formatted data from file descriptor (fscanf(fid, fmt, size)).
nk::runtime::fprintf
std::size_t fprintf(::nk::Engine &engine, Span< const Value > args)
Formats and writes text to engine stdout or open file descriptor.
nk::runtime::textscan
void textscan(::nk::Engine &engine, Span< const Value > args, size_t nargout, Span< Value > outs)
Reads tabular data from open file descriptor or string (textscan(fid, fmt)).
nk::runtime::disp
void disp(::nk::Engine &engine, Span< const Value > args)
Displays value to engine standard output (disp(v)).
