所以It is always recommended to declare a function before its use so that we don’t see any surprises when the program is run (Seethisfor more details).
As aparameter to a function: int my_function(returnType(*parameterName)(parameterTypes)); (example code) As areturn value from a function: returnType(*my_function(int, ...))(parameterTypes); (example code) As acast(but try not to cast functions): ...

DECLARE_NAPI_FUNCTION头文件 头文件调用函数 C文件的头文件及调用函数位置及gcc使用 C文件示例 #include<stdio.h>//头文件的作用? int main(int argc,char * *argv[]) { if(argc > 2){ printf(“HELLO, %s!\n”,argv[1]);//调用函数在哪里?
// declare a function called drawLine; don't mangle// its nameextern "C"void drawLine(int x1, int y1, int x2, int y2);不要以为有一个extern 'C',那么就应该同样有一个extern 'Pascal'和extern 'FORTRAN'。没有,至少在C++标准中没有。不要将extern 'C'看作是申明这个函数是用C语言写的,...

The function is the fundamental modular unit in C. A function is usually designed to perform a specific task, and its name often reflects that task. A function contains declarations and statements. This section describes how to declare, define, and call C functions. Other topics discussed are:...
