.SH "NAME"
pam_end \- termination of PAM transaction
.SH "SYNOPSIS"

.ft B
.nf
#include <security/pam_appl\&.h>
.fi
.ft
.HP \w'int\ pam_end('u
.BI "int pam_end(pam_handle_t\ *" "pamh" ", int\ " "pam_status" ");"
.SH "DESCRIPTION"
.PP
The
\fBpam_end\fR
function terminates the PAM transaction and is the last function an application should call in the PAM context\&. 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is no longer valid and all memory associated with it will be invalid\&.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\*(Aqd 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\*(Aqs 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"
.PP
PAM_SUCCESS
.RS 4
Transaction was successful terminated\&.
.RE
.PP
PAM_SYSTEM_ERR
.RS 4
System error, for example a NULL pointer was submitted as PAM handle or the function was called by a module\&.
