I,

I come across a strange problem when using strlcat, as follows:

static int get_path(char *parent, char * file){
	int parent_len = strlen(parent);
	int file_len = strlen(file);
	if(parent_len + file_len > 256) {
		return 0;
	}
	int ret = strlcat(parent, file, file_len);
}

int main(int argc, char *argv[]) {
	char path[256];
	char file[256];
	snprintf(path, 256, "%s", "./parent/");
	snprintf(file, 256, "%s", "test.dat");
	get_path(path, file);
	cout << path << endl;
	cout.flush();
}

The output is :

./parent/


The problem is why the output is "./parent/"? Is it supposed to be "./parent/test.dat"?

Thanks
