+.PP
+If the second argument is a printable ASCII character, the driver places it
+in the current position in the current field. If it is one of the forms
+requests listed above, that request is executed.
+.PP
+If the second argument is neither printable ASCII nor one of the above
+pre-defined form requests, the driver assumes it is an application-specific
+command and returns \fBE_UNKNOWN_COMMAND\fR. Application-defined commands
+should be defined relative to \fBMAX_COMMAND\fR, the maximum value of these
+pre-defined requests.
+.SH RETURN VALUE
+\fBform_driver\fR return one of the following error codes:
+.TP 5
+\fBE_OK\fR
+The routine succeeded.
+.TP 5
+\fBE_SYSTEM_ERROR\fR
+System error occurred (see \fBerrno\fR).
+.TP 5
+\fBE_BAD_ARGUMENT\fR
+Routine detected an incorrect or out-of-range argument.
+.TP 5
+\fBE_BAD_STATE\fR
+Routine was called from an initialization or termination function.
+.TP 5
+\fBE_NOT_POSTED\fR
+The form has not been posted.
+.TP 5
+\fBE_UNKNOWN_COMMAND\fR
+The form driver code saw an unknown request code.
+.TP 5
+\fBE_INVALID_FIELD\fR
+Contents of field is invalid.
+.TP 5
+\fBE_REQUEST_DENIED\fR

+Version 7 or BSD versions.
