These functions get and set the menu user pointer field. .SH RETURN VALUE Except for \fBmenu_userptr\fR (which returns \fBNULL\fR on error), each function returns one of the following: .TP 5 \fBE_OK\fR The routine succeeded. .TP 5 \fBE_SYSTEM_ERROR\fR System error occurred (see \fBerrno\fR). .SH SEE ALSO \fBcurses\fR(3), \fBmenu\fR(3). .SH NOTES The header file \fB\fR automatically includes the header file \fB\fR. .SH PORTABILITY These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions. The user pointer should be a void pointer. We leave it as a char pointer for SVr4 compatibility. .SH AUTHORS Juergen Pfeifer.
