NAME

       cd_nmconv - Sets or gets CD-ROM file name conversions

LIBRARY

       Rock Ridge and X/Open Extensions to the CDFS library (libcdrom.so, libcdrom.a)

SYNOPSIS

       #include <sys/cdrom.h> int cd_nmconv (	   char *path,	    int cmd,	  int *flag );

PARAMETERS

	      Points to a mount-point of a CD-ROM file system.

	      Can be set to either {CD_SETNMCONV} to set or {CD_GETNMCONV} to get the name conversion for file names on a mounted CD-ROM.

	      Used in conjunction with cmd, and can be one of the following:

	      {CD_NOCONV}

	      No conversion.  This is the default when the CD-ROM is first mounted.

	      {CD_LOWER}

	      File  or	directory names on the CD-ROM File System are converted to lowercase when represented in the XSI file hierarchy.  In addi-
	      tion, if a file or directory name contains no File Name Extension, SEPARATOR 1, a dot (.), is not represented in the XSI file  hier-
	      archy.

	      {CD_NOVERSION}

	      The  version  number and SEPARATOR 2, a semi-colon (;), of a file or directory name on the CD-ROM File System are not represented in
	      the XSI file hierarchy.

	      Note that {CD_LOWER} and {CD_NOVERSION} may be bitwise-inclusive OR-ed.

DESCRIPTION

       The cd_nmconv routine sets of gets the name conversion *flag for file names on a mounted CD-ROM.

RESTRICTIONS

       Setting a file name conversion is restricted to users with the appropriate privileges.  This function is intended to be used to set a  file
       name  conversion only directly after the CD-ROM is mounted and before its files and directories are accessed.  Attempting to use this func-
       tion to set a file name conversion after files or directories on the CD-ROM have been accessed may produce unpredictable results.

RETURN VALUES

       If successful, the value zero is returned.
       If unsuccessful, the integer -1 is returned and errno is set to indicate the error.

ERRORS

       The function will fail if: Search permission is denied for a directory in *path or read permission  is  denied  on  the	mount-point.   The
       address of *flag or *path is invalid.  A signal was caught during execution of the function.  The argument *path does not point to a mount-
       point of a CDROM File System.
       The value of cmd or *flag is invalid.  {OPEN_MAX} file descriptors are currently open in the calling process.

	      [Tru64 UNIX]  Either the OPEN_MAX value or the per-process soft descriptor limit is checked.  The length of the *path string exceeds
	      {PATH_MAX},  or a pathname component is longer than {NAME_MAX} while {_POSIX_NO_TRUNC} is in effect.  The system file table is full.
	      A component of *path does not exist, or the *path argument points to an empty string.  A component of the  *path	prefix	is  not  a
	      directory.  The user does not have the appropriate privileges to set values.
