Member Function Documentation

Print()

template<Print::Text Source, typename... Args>

static int LibXR::STDIO::Print ( Args &&... args )

inlinestatic

将一个编译期 brace 字面量打印到当前 STDIO 输出 / Print one compile-time brace literal to the active STDIO output

Template Parameters

Source	编译期 brace 格式字面量 / Compile-time brace format literal
Args	调用点运行时参数类型列表 / Call-site runtime argument types

Parameters

args	参与本次打印的运行时参数 / Runtime arguments used by the current print

Returns

返回当前 STDIO 流实际保留并提交的字节数；若会话建立或提交失败则返回 -1 / Returns the byte count actually retained and committed to the current STDIO stream; returns -1 on session or commit failure

Definition at line 227 of file stdio.hpp.

  {
    constexpr LibXR::Format<Source> format{};
    return RunCompiled(format, std::forward<Args>(args)...);
  }

Template Parameters

Source	编译期 printf 格式字面量 / Compile-time printf format literal
Args	调用点运行时参数类型列表 / Call-site runtime argument types

Parameters

args	参与本次打印的运行时参数 / Runtime arguments used by the current print

Returns
