chown() COHERENT System Call chown() Change ownership of a file cchhoowwnn(_f_i_l_e, _u_i_d, _g_i_d) cchhaarr *_f_i_l_e ; sshhoorrtt _u_i_d, _g_i_d; chown changes the owner of file to user id uid and group id gid. To change only the user id without changing the group id, stat should be used to determine the value of gid to pass to chown. chown is restricted to the superuser, because granting the ordi- nary user the ability to change the ownership of files might cir- cumvent file space quotas or accounting based upon file owner- ship. chown returns -1 for errors, such as nonexistent file or the caller not being the superuser. ***** See Also ***** chmod(), COHERENT system calls, passwd, stat() COHERENT Lexicon Page 1
