+\fBpam_start\fR(3)
+and
+\fBpam_conv\fR(3))\. The name of the authenticated user will be present in the PAM item PAM_USER\. This item may be recovered with a call to
+\fBpam_get_item\fR(3)\.
+.PP
+The
+\fIpamh\fR
+argument is an authentication handle obtained by a prior call to pam_start()\. The flags argument is the binary or of zero or more of the following values:
