+.SH "DESCRIPTION"
+.PP
+The
+\fBpam_end\fR
+function terminates the PAM transaction and is the last function an application should call in the PAM contenxt. Upon return the handle
+\fIpamh\fR
+is no longer valid and all memory associated with it will be invalid.
+.PP
+The
+\fIpam_status\fR
+argument should be set to the value returned to the application by the last PAM library call.
+.PP
+The value taken by
+\fIpam_status\fR
+is used as an argument to the module specific callback function,
+\fBcleanup()\fR
+(See
+\fBpam_set_data\fR(3)
+and
+\fBpam_get_data\fR(3)). In this way the module can be given notification of the pass/fail nature of the tear\-down process, and perform any last minute tasks that are appropriate to the module before it is unlinked. This argument can be logically OR'd with
+\fIPAM_DATA_SILENT\fR
+to indicate to indicate that the module should not treat the call too seriously. It is generally used to indicate that the current closing of the library is in a
+\fBfork\fR(2)ed process, and that the parent will take care of cleaning up things that exist outside of the current process space (files etc.).
+.PP
+This function
+\fIfree\fR's all memory for items associated with the
+\fBpam_set_item\fR(3)
+and
+\fBpam_get_item\fR(3)
+functions. Pointers associated with such objects are not valid anymore after
+\fBpam_end\fR
+was called.
+.SH "RETURN VALUES"
+.TP 3n
+PAM_SUCCESS
+Transaction was successful terminated.
+.TP 3n
+PAM_SYSTEM_ERR
+System error, for example a NULL pointer was submitted as PAM handle or the function was called by a module.
