C++ (Cpp) s_fread Examples

Example #1

File: libsrj.c Project: orionmiller/selective_reject

//DOES NOT APPROPRIATELY MAKE A PACKET YET
void file_fill_frame(window *Window, file *File, uint32_t seq)
{
    static uint8_t data[MAX_BUFF_SIZE];
    frame *Frame = Window->Frame[get_frame_num(Window, seq)];
    uint32_t data_len = s_fread(data, sizeof(uint8_t), Window->buffsize, File->fp);

    if (data_len == 0)
        Frame->state = FRAME_EMPTY;
    else
    {
        create_pkt(Frame->Pkt, DATA, seq, data, data_len);
        Frame->state = FRAME_FULL;
    }

    printf("Pkt data_len %u\n", data_len);

    if (feof(File->fp))
        Window->eof = TRUE;

    if (Window->eof)
        printf("File is now at EOF\n");
