NAME

       cd_type - Determines the type of file system recorded on a CD-ROM

LIBRARY

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

SYNOPSIS

       #include <sys/cdrom.h> int cd_type (	 char *path );

PARAMETERS

	      Points  to a pathname naming a file or directory within the CD-ROM File  System hierarchy, or to a pathname naming the block special
	      file for the CD-ROM File System.

DESCRIPTION

       The cd_type routine determines the type of file system recorded on the CD-ROM pointed to by *path.

RETURN VALUES

       If successful, the function returns one of the following values, which are defined in cdfs/xcdr.h, an include  file  that  is  called  into
       sys/cdrom.h:

       {CD_ISO9660} CD-ROM is recorded according to ISO 9660.

       {CD_HSG} CD-ROM is recorded according to High Sierra Group.

       {CD_RRIP}  CD-ROM is recorded according to ISO 9660 with the Rock Ridge Extension.

       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 and execute permission are denied for the named
       file, or read permission is denied on the block special file pointed to by *path.  The address of *path is invalid.  A  signal  was  caught
       during  execution  of  the  function.   The  argument  *path  points  to  a file or directory that is not within the CD-ROM file hierarchy.
       {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 CD-ROM is not in the drive, or a read error occurred.

	      The named file is a block special file and the device associated with the special file does not exist.
