用man可以比较方便查看函数需要什么头文件和库比如:
NAME
  printf, fprintf, sprintf, snprintf, asprintf, vprintf, vfprintf,
  vsprintf, vsnprintf, vasprintf -- formatted output conversion

LIBRARY
  Standard C Library (libc, -lc)

SYNOPSIS
  #include <stdio.h>

================
NAME
  sin, sinf -- sine functions

LIBRARY
  Math Library (libm, -lm)

SYNOPSIS
  #include <math.h>

  double
  sin(double x);

  float
  sinf(float x);
