dpns_chmod - change access mode of a DPNS directory/file in the name server
#include <sys/types.h> #include "dpns_api.h" int dpns_chmod (const char *path, mode_t mode)
dpns_chmod sets the access permission portion of the mode of a DPNS directory/file in the name server to the bit pattern in mode. path specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname. mode is constructed by OR'ing the bits defined in <sys/stat.h> under Unix or "statbits.h" under Windows/NT: S_ISUID 0004000 set user ID on execution S_ISGID 0002000 set group ID on execution S_ISVTX 0001000 sticky bit S_IRUSR 0000400 read by owner S_IWUSR 0000200 write by owner S_IXUSR 0000100 execute/search by owner S_IRGRP 0000040 read by group S_IWGRP 0000020 write by group S_IXGRP 0000010 execute/search by group S_IROTH 0000004 read by others S_IWOTH 0000002 write by others S_IXOTH 0000001 execute/search by others The effective user ID of the process must match the owner of the file or the caller must have ADMIN privilege in the Cupv database. If a directory is writable and has the sticky bit set, files/directories within that directory can be removed or renamed only if: the effective user ID of the requestor matches the owner ID of the file or the effective user ID of the requestor matches the owner ID of the directory or the file is writable by the requestor or the requestor has ADMIN privilege in the Cupv database.
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
EPERM The effective user ID does not match the owner of the file and the caller does not have ADMIN privilege in the Cupv database. ENOENT The named file/directory does not exist or is a null pathname. EACCES Search permission is denied on a component of the path prefix. EFAULT path is a NULL pointer. ENOTDIR A component of path prefix is not a directory. ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error. ENSNACT Name server is not running or is being shutdown.
