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 direc-
       tory 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.
