[Dev-C++] STL sort() problem

[Abhijit S. <mu...@gm...>]

Greets.

I'm using a vector of a structure pointer (I use dynamic allocation), like
so:

    vector<PlsLine *> lines;

and PlsLine is a structure:

typedef struct _PlsLine
{
    char    *fn;            // Full filename (c:\foo\bar.mp3)
    char    *filename;      // Filename part only (bar.mp3)
    int     size;           // Filesize
} PlsLine;

I need to sort this, and I call sort() like this:

    sort(lines.begin(), lines.end());

However, sort() uses the comparison operators (< and >), and I can't define
them for pointers... The compiler flags this:

    bool operator <(const PlsLine *&left, const PlsLine *&right)

as an error. It says it should be a class or enumerated type. I tried doing
this:

    bool operator <(const PlsLine &left, const PlsLine &right)

and the compile worked, but it doesn't seem to sort.
Any work-around?
