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 hi- erarchy. 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_MAX- DRECL} 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 indi- cate 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. [DIGITAL] Either the OPEN_MAX value or the per-process soft de- scriptor limit is checked. The length of the *path string ex- ceeds {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.
