    unsigned char cmd,
    unsigned char size,

A cmd_queue is a contiguous array of SceOledCmd of different sizes. To get the next SceOledCmd of a queue, do: 

struct SceOledCmd *cur_cmd = ...
struct SceOledCmd *next_cmd = &(cur_cmd->buf) + cur_cmd->size;

if (next_cmd->cmd == 0 || next_cmd->cmd == 255) {...} // End of queue
