NAME¶

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.
