cd_drec(3)						     Library Functions Manual							cd_drec(3)

NAME

       cd_drec, cd_cdrec - Reads the Directory Record from a CD-ROM directory

LIBRARY

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

SYNOPSIS

       #include  <sys/cdrom.h>	int  cd_drec  (       char *path,      int fsec,      struct iso9660_drec *drec ); int cd_cdrec (      char *path,
	    int fsec,	   char *addr );

PARAMETERS

	      Points to a file or directory within the CD-ROM File System hierarchy.

	      Specifies the File Section of the file or directory pointed to by *path, with the numbering beginning at one.  If fsec is set to -1,
	      the last File Section of the named file or the only File Section of the named directory is assumed.

	      Points  to  the iso9660_drec structure that holds the contents of the Directory Record associated with the file or directory pointed
	      to by *path.  The iso9660_drec 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_cdrec copies the complete Directory Record that is recorded on the CD-ROM.

DESCRIPTION

       The cd_drec routine fills the *drec structure with the contents of the Directory Record that is associated with a file or directory pointed
       to by *path.

       The  cd_cdrec  function	copies	the  complete Directory Record from the CD-ROM to the address pointed to by *addr.  The user must allocate
       {CD_MAXDRECL} bytes for the Directory Record.  The variable {CD_MAXDRECL} 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 file or directory
       pointed to by *path.  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.

	      The value of fsec 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 CD-ROM is not in the drive, or a read error occurred.
