rfio_chown - change owner and group of a directory/file
SYNOPSIS
#include <sys/types.h>
#include "rfio_api.h"
int rfio_chown (const char *path, uid_t new_uid, gid_t new_gid)
DESCRIPTION
rfio_chown sets the owner and the group of a directory/file to the numeric values in owner and group respectively. If owner or group is
specified as -1, rfio_chown() does not change the corresponding ID of the file.
path specifies the logical pathname relative to the current directory or the full pathname.
The effective user ID of the process must match the owner of the file or 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
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.
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.
EINVAL new_uid or new_gid is invalid.
ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.
SENOSHOST Host unknown.
SENOSSERV Service unknown.
SETIMEDOUT Timed out.
SECONNDROP Connection closed by remote end.
SECOMERR Communication error.
