Two different functions but with the same name in separate libraries

clliao.tw

I have two libraries, named a.lib and b.lib. Both libraries have a function char test(void), but return different characters.

a.c (a.lib)

char test(void);
char test(void) {
return 'a';
}

b.c (b.lib)

char test(void);
char test(void) {
return 'b';
}

I create a project link these two libraries and call test() in main() function.

main.c

char test(void);
int main()
{
char c = test();
return 0;
}

I expected it should be "Error: L6200E: Symbol multiply defined" error, but " 0 errors".

Why is there no link error?

Thanks for the reply.
