15 This function together with the pam_set_data(3) function is useful to
16 manage module-specific data meaningful only to the calling PAM module.
17
18 The pam_get_data function looks up the object associated with the
19 (hopefully) unique string module_data_name in the PAM context specified
20 by the pamh argument. A successful call to pam_get_data will result in
21 data pointing to the object. Note, this data is not a copy and should
22 be treated as constant by the module.

25 PAM_SUCCESS
