前面贴的是主要的一些命令，所以再加一组合就可以完成player的功能了... /************************************************************************* name: AudioCDPlayer return: 0 - sucess *************************************************************************/ static int AudioCDPlayer(driveinfo Drive) { bool Load=false, Disc=false, Continue=false; int Temp, Tries, CurrTrack=0, Key; // Show Help first ShowHelp(); // Check tray status Temp=atapiChkTrayIsOpen(Drive); if (Temp == 0) // Tray is closed { // Read Disc TOC printf("\nTrying to read Audio CD Table-Of-Contents ...\n"); // 5 times max for retry for(Tries=5; Tries>0; Tries--) { Temp=atapiTOC(Drive); if (Temp == 0 ) { break; } delay(2000); } if (Temp == 0) // Disc is Ready { Disc=true; } else { printf("No Disc!"); } } else // Tray is opened , can Load { Load=true; } if(Disc == true ) // 找到碟片，且读Toc OK { printf ("Disc is READY\n"); } while(1) { Key=bioskey(0); if (Key == 0x0000) // Ctrl-Break时强行终止 { return(0); } //**** Esc or Q -> quit ************ if(Key == 0x011b \|\| Key == 0x1071 \|\| Key == 0x1051) { clrscr(); break; } //****** e or E -> load/eject **** else if( Key==0x1265 \|\| Key==0x1245) { if(Load) { printf ("Please wait for LOAD disc...\n"); } else { printf ("EJECT....\n"); } atapiEject(Drive, Load); //Load=!Load; Load=(Load==true ? false : true); goto LoadToc; } //****** t or T -> load TOC ***** else if(( Key==0x1474 \|\| Key==0x1454) && Load==false) { LoadToc: printf ("WAITING ....\n"); CurrTrack=0; // init variable NumTracks=0; for(Tries=5; Tries>0; Tries--) { Temp=atapiTOC(Drive); if (Temp == 0 \|\| Load == true) { break; } delay(2000); } if (Temp != 0) { printf ("NO DISC\n"); Disc=false; } else { printf ("Disc is READY\n"); printf ("Track %d of %d\n", (Temp==0 ?
