RFIO_CHMOD(3) Rfio Library Functions RFIO_CHMOD(3) NAME
rfio_chmod, rfio_fchmod - change access mode of a directory/file SYNOPSIS
#include <sys/types.h> #include "rfio_api.h" int rfio_chmod (const char *path, mode_t mode); int rfio_fchmod (int s, mode_t mode); DESCRIPTION
rfio_chmod sets the access permission portion of the mode of a directory/file to the bit pattern in mode. rfio_fchmod is identical to rfio_chmod but works on the file descriptor s returned by rfio_open. path specifies the logical pathname relative to the current directory or the full pathname. mode is constructed by OR'ing the bits defined in <sys/stat.h> under Unix or "statbits.h" under Windows/NT: 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 be super-user. 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 is super-user. RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately. ERRORS
EPERM The effective user ID does not match the owner of the file and is not super-user. ENOENT The named file/directory does not exist or is a null pathname. EBADF s is not a valid file descriptor. EACCES Search permission is denied on a component of the path prefix or write permission on the file itself is denied. 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. SEE ALSO

RFIO_RENAME(3) Rfio Library Functions RFIO_RENAME(3) NAME
rfio_rename - rename a file or directory SYNOPSIS
#include <sys/types.h> #include "rfio_api.h" int rfio_rename (const char *oldpath, const char *newpath) DESCRIPTION
rfio_rename renames a file or directory. oldpath and newpath must be of the same type, i.e. both regular files or both directories. If newpath exists already, it will be removed before the rename takes place. If newpath is a directory, it must be empty. When renaming a directory, newpath must not be a descendant of oldpath, i.e. newpath must not contain a path prefix that names oldpath. Write permission is required on both parents. If oldpath is a directory, write permission is required on it and if newpath is an existing directory, write permission is also required on it. If any of the parents has the sticky bit S_ISVTX set, either the effective user ID of the requestor must match the owner ID of the file or the effective user ID of the requestor must match the owner ID of the directory or the file must be writable by the requestor or the requestor must be super-user. RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately. ERRORS
ENOENT A component of oldpath prefix does not exist or oldpath or newpath is a null pathname. EACCES Search permission is denied on a component of the path prefixes or write permission on the parent directories is denied or oldpath is a directory and write permission is denied on oldpath or newpath. EFAULT oldpath or newpath is a NULL pointer. EEXIST newpath is an existing directory and is not empty. ENOTDIR A component of the path prefixes is not a directory or oldpath is a directory and newpath is an existing regular file. EISDIR newpath is a directory while oldpath is a regular file. EINVAL newpath is a descendant of oldpath. ENAMETOOLONG The length of oldpath or newpath exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN. SENOSHOST Host unknown. SENOSSERV Service unknown. SECOMERR Communication error. ERFXHOST Cross-host rename is not supported. SEE ALSO
