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.

[DIGITAL]  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.
