+.SH "DESCRIPTION"
+.PP
+The
+\fBpam_get_user\fR
+function returns the name of the user specified by
+\fBpam_start\fR(3). If no user was specified it what
+\fBpam_get_item (pamh, PAM_USER, ... );\fR
+would have returned. If this is NULL it obtains the username via the
+\fBpam_conv\fR(3)
+mechanism, it prompts the user with the first non\-NULL string in the following list:
+.TP 3
+\(bu
+The
+\fIprompt\fR
+argument passed to the function.
+.TP
+\(bu
+What is returned by pam_get_item (pamh, PAM_USER_PROMPT, ... );
+.TP
+\(bu
+The default prompt: "login: "
+.PP
+By whatever means the username is obtained, a pointer to it is returned as the contents of
+\fI*user\fR. Note, this memory should
+\fInot\fR
+be
+\fIfree()\fR'd or
+\fImodified\fR
+by the module.

+This function sets the
+\fIPAM_USER\fR
+item associated with the
+\fBpam_set_item\fR(3)
+and
+\fBpam_get_item\fR(3)
+functions.
