- .br
- The
- .I cdrom.h\^
- header contains the RRIP constant definitions for the RRIP library functions.
- If XCDR is supported, this header file will also contain
- the XCDR constants and structure declarations for the XCDR library functions.
- .sp
- The function
- .I cd_setdevmap()\^
- uses the following values for the argument
- .I cmd:\^
- .sp
- .TS
- center;
- l l.
- CD_SETDMAP Set device file mapping
- CD_UNSETDMAP Unset device file mapping
- .TE

- If an implementation imposes a limit on the number of device file mappings,
- they will be defined by the following symbolic name.
- The definition of this symbolic name may be omitted from
- .I <sys/cdrom.h>\^
- if the actual value of the limit is indeterminate but greater than
- the stated minimum.
- Applications should therefore only use this symbol in code
- conditionally compiled on the existence of this symbol.

- .H 2 "Recommendations for CD-ROM Publishers"
- .sp
- Unless the CD-ROM is targetted at a specific collection of systems, the
- values for major and minor numbers of device files will not identify
- the correct values on the receiving system.
- Also the range of values for device file major and minor numbers
- that a system can handle might be smaller than what can be recorded
- on the CD-ROM.
- When producing a CD-ROM to be used on various systems, it is recommended
- that the publisher number the device major and minor numbers consecutively
- starting at 0 and provide the System Administrator with sufficient
- information to map each recorded major and minor number to the appropriate
- values for the target system.
