| .SH "DESCRIPTION" |
| .PP |
| Opens a CD-ROM drive for access\&. It returns a \fI\fBSDL_CD\fR\fR structure on success, or \fBNULL\fP if the drive was invalid or busy\&. This newly opened CD-ROM becomes the default CD used when other CD functions are passed a \fBNULL\fP CD-ROM handle\&. |
| .PP |
| Drives are numbered starting with 0\&. Drive 0 is the system default CD-ROM\&. |
