188 This function together with the
189 \fBpam_set_data\fR(3)
190 function is useful to manage module\-specific data meaningful only to the calling PAM module\&.
194 function looks up the object associated with the (hopefully) unique string
195 \fImodule_data_name\fR
196 in the PAM context specified by the
198 argument\&. A successful call to
202 pointing to the object\&. Note, this data is
204 a copy and should be treated as
211 Data was successful retrieved\&.
216 A NULL pointer was submitted as PAM handle or the function was called by an application\&.
221 Module data not found or there is an entry, but it has the value NULL\&.
