| 155 ><P | |
| 156 >You use this API to perform all the basic functions of a CD player, | |
| 157 including listing the tracks, playing, stopping, and ejecting the CD-ROM. | |
| 158 (Currently, multi-changer CD drives are not supported.)</P | |
| 159 ><P | |
| 160 >Before you call any of the SDL CD-ROM functions, you must first call | |
| 161 "<TT | |
| 162 CLASS="FUNCTION" | |
| 163 >SDL_Init(SDL_INIT_CDROM)</TT | |
| 164 >", which scans the system for | |
| 165 CD-ROM drives, and sets the program up for audio control. Check the | |
| 166 return code, which should be <SPAN | |
| 167 CLASS="RETURNVALUE" | |
| 168 >0</SPAN | |
| 169 >, to see if there | |
| 170 were any errors in starting up.</P | |
| 171 ><P | |
| 172 >After you have initialized the library, you can find out how many drives | |
| 173 are available using the <TT | |
| 174 CLASS="FUNCTION" | |
| 175 >SDL_CDNumDrives()</TT | |
| 176 > function. | |
| 177 The first drive listed is the system default CD-ROM drive. After you have | |
| 178 chosen a drive, and have opened it with <TT | |
| 179 CLASS="FUNCTION" | |
| 180 >SDL_CDOpen()</TT | |
| 181 >, | |
| 182 you can check the status and start playing if there's a CD in the drive.</P | |
| 183 ><P | |
| 184 >A CD-ROM is organized into one or more tracks, each consisting of a certain | |
| 185 number of "frames". Each frame is ~2K in size, and at normal playing speed, | |
| 186 a CD plays 75 frames per second. SDL works with the number of frames on a | |
| 187 CD, but this can easily be converted to the more familiar minutes/seconds | |
| 188 format by using the <TT | |
| 189 CLASS="FUNCTION" | |
| 190 >FRAMES_TO_MSF()</TT | |
| 191 > macro.</P | |
