This header is part of the Input/Output library.

Functions
print (C++23)	prints to stdout or a file stream using formatted representation of the arguments (function template)
println (C++23)	same as std::print except that each print is terminated by additional new line (function template)
vprint_unicodevprint_unicode_buffered (C++23)	prints to Unicode capable stdout or a file stream using type-erased argument representation (function)
vprint_nonunicodevprint_nonunicode_buffered (C++23)	prints to stdout or a file stream using type-erased argument representation (function)

Synopsis

namespace std {
  // print functions
  template<class... Args>
    void print(format_string<Args...> fmt, Args&&... args);
  template<class... Args>
    void print(FILE* stream, format_string<Args...> fmt, Args&&... args);
 
  template<class... Args>
    void println(format_string<Args...> fmt, Args&&... args);
  void println();
  template<class... Args>
    void println(FILE* stream, format_string<Args...> fmt, Args&&... args);
  void println(FILE* stream);
 
  void vprint_unicode(string_view fmt, format_args args);
  void vprint_unicode(FILE* stream, string_view fmt, format_args args);
 
  void vprint_unicode_locking(FILE* stream, string_view fmt, format_args args);
 
  void vprint_nonunicode(string_view fmt, format_args args);
  void vprint_nonunicode(FILE* stream, string_view fmt, format_args args);
 
  void vprint_nonunicode_locking(FILE* stream, string_view fmt, format_args args);
}
