printfライブラリ

printf 相当関数

本 TWENETstgs ではオープンソースによるprintfライブラリを利用した fprintf, vfprintf, sprintf 相当関数を定義しています。

int TWE_fprintf(TWE_tsFILE *fp, const char *format, ...);
int TWE_vfprintf(TWE_tsFILE *fp, const char *format, va_list va);
#define TWE_snprintf(out,siz,fmt,...) snprintf_(out,siz,fmt,__VA_ARGS__)

// \brief Tiny printf, sprintf and snprintf implementation, optimized for speed on
//        embedded systems with a very limited resources.
//        Use this instead of bloated standard/newlib printf.
//        These routines are thread safe and reentrant.
