#include <stdio.h>#include <stdarg.h>void MyPrintf(char *format, ...){ va_list ap; va_start(ap, format); vprintf(format, ap); va_end(ap);}void Error(char *format, ...){ va_list ap; va_start(ap, format); fprintf(stdout, "err:"); vprintf(format, ap); va_end(ap);}int main(){ MyPrintf("test printf %d %s /n", 1, "hell"); Error("test Error %d %s /n", 1, "hell"); return 0;}

输出结果：
