file-handling

I've been writing a small C application that operates on files, and I've found that I have been copy+pasting this code around my functions:

char fullpath[PATH_MAX];
fullpath[0] = '\0';
strcat(fullpath, BASE_PATH);
strcat(fullpath, subdir);
strcat(fullpath, "/");
strcat(fullpath, filename);

// do something with fullpath...

Is there a better way? The first thought that comes to mind is to create a macro but I'm sure this is a common problem in C, and I'm wondering how others have solve it.

However, I cannot use the this.get() method to obtain the original string; doing so triggers a this.get is not… >>> More

Hello, I need to index specific strings with other strings and I can't really find a good way to do so. I tried to use tr1::unordered_map, but I'm having some difficulties using it.
