C++ (Cpp) get_label_name Examples

Example #1

TEST(FirstPass, get_label_name) {
    char a[] = "NAME: .string \"Linus\"";
    char b[] = ".data +7,-57,  17 , 9";
    char c[] = "DATA: .data +7,-57,  17 , 9";
    char d[] = ".entry HELLO";

    EXPECT_STREQ(get_label_name(a), "NAME");
    EXPECT_STREQ(get_label_name(b), NULL);
    EXPECT_STREQ(get_label_name(c), "DATA");
    EXPECT_STREQ(get_label_name(d), NULL);
