cd_suf(3) Library Functions Manual cd_suf(3) NAME
cd_suf - Read System Use Field from a specified System Use Area on a Rock Ridge format CD-ROM LIBRARY
CD-ROM library (libcdrom.so, libcdrom.a) SYNOPSIS
#include <sys/cdrom.h> int cd_suf (path, fsec, signature, index, buf, buflen) char *path; int fsec; char signature[2]; int index; char *buf; int buflen; DESCRIPTION
Returns a System Use Field in the System Use Area for path. Points to a file or directory within the CD-ROM file hierarchy. Specifies the File Section of that file. The numbering starts with one. If fsec is set to -1, the System Use Area of the last File Section of that file is assumed. The 2-byte signature to look for and return from the System Use Area. The occurrence of signature to return. If signature is a NULL pointer, returns the System Use Field specified by index starting from the beginning of the System Use Area. Otherwise, returns the occurrence of signature specified by index. The index number of the first System Use Field of any signature is one. The buffer in which to place the System Use Field. The buffer length of buf. RETURN VALUES
The cd_suf function will return the number of bytes placed in buf if successful. The cd_suf function will return 0 if the signature field is not found. In case of error, -1 is returned and errno is set to indicate the error. ERRORS
The cd_suf() function will fail if: Search permission is denied for a component of the path prefix or read permission on the file or direc- tory pointed to by path is denied. 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. A component of path does not exist or the path argument points to an empty string. The File Section indicated by fsec has no System Use Area. A component of the path prefix is not a directory. The address of buf, signature, or path is invalid. The value of fsec, index, or buflen is invalid. The argument path points to a file or directory not within a CD-ROM file hierar- chy. The Volume containing the File Section indicated by fsec is not mounted. The CD-ROM is not in the drive or a read error occurred. A signal was caught during the cd_suf() function. {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 system file table is full. RELATED INFORMATION
