c - 使用c创建h文件

Question

我有一个定义了 typedef 结构的源文件:

typedef struct {
    unsigned int seed;
} generator;

generator *create() {
    generator *g = (generator*)malloc(sizeof(generator));
    g->seed = time(0);
    
    return g;
}

void set_seed(generator *g, unsigned int s) {
    g->seed = s;
}

unsigned int rand_int(generator *g) {
    return g->seed = (a * g->seed) % m;
} 

我需要编写头文件，.h文件。但我不断得到

Undefined symbols for architecture x86_64:
  "_main", referenced from:
     implicit entry/start for main executable
ld: symbol(s) not found for architecture x86_64

为了避免此错误，请帮助我编写 .h 文件。

将此代码片段添加到您的代码中:

int main(void) {}

您的程序中缺少main函数。
