hi,
can someone explain this to me :
0: using namespace ldm;
1: struct cmd_parse_t {
2: char flag;
3: void (*taskfunc)(ldm::diskio& dev, int argc, char** argv);
4: bool readonly;
5: };
what does line 3 do ? is it a pointer to a function or something else ?

Exactly! It's a pointer to function.
Prototype looks like follow:
void taskfunc(ldm::diskio& dev, int argc, char** argv);
