NAME

cd_ptrec, cd_cptrec - Reads the Path Table Record from the CD-ROM Path Table  

LIBRARY

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

SYNOPSIS

#include <sys/cdrom.h> int cd_ptrec (        char *path,
       struct iso9660_ptrec *ptrec );
int cd_cptrec (        char *path,
       char *addr );
 

PARAMETERS

Points to a file or directory within the CD-ROM File System hierarchy.
Points to the iso9660_ptrec structure that holds the contents of the Path Table Record associated with the file or directory pointed to by *path. The iso9660_ptrec structure is defined in cdfs/xcdr.h, an include file that is called into sys/cdrom.h
Specifies the address to which the function cd_cptrec copies the complete Path Table Record that is recorded on the CD-ROM.
 

DESCRIPTION

The cd_ptrec routine fills the *ptrec structure with the contents of the Path Table Record associated with the directory that is pointed to by *path.

The cd_cptrec function copies the complete Path Table Record that is recorded on the CD-ROM to the address pointed to by *addr. The user must allocate {CD_MAXPTRECL} bytes for the Path Table Record. The variable {CD_MAXPTRECL} is defined in cdfs/xcdr.h, an include file that is called into sys/cdrom.h.  

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 for the named directory. The address of *path or *addr 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.
