我收到一个“错误：重新定义”符号，即使我之前在文件中使用了相同的语法，

Question

I am creating a function stub (for a function foo_print_stats()) for a unit test,and have written the following code:

static void my_foo_stats(foo_fs_t * const fsys) {
    return;
}
#undef foo_print_stats
#define foo_print_stats my_foo_stats

I keep getting the error "redefininiton of my_foo_stats". I have tried changing the name to something else, to no avail. The parameters for my_foo_stats are the exact same as those passed to foo_print_stats. I am confused because I have used the exact same syntax many times int the same file and it has all worked.

Realized that the file where the function was initially being defined was getting included below where I was trying to redefine it. thanks to @Tom Karzes for advice
