| 31 | .TH mitem_userptr 3X ""
|
|---|
| 32 | .SH NAME
|
|---|
| 33 | \fBmitem_userptr\fR - associate application data with a menu item
|
|---|
| 34 | .SH SYNOPSIS
|
|---|
| 35 | \fB#include <menu.h>\fR
|
|---|
| 36 | .br
|
|---|
| 37 | int set_item_userptr(ITEM *item, void *userptr);
|
|---|
| 38 | .br
|
|---|
| 39 | void *item_userptr(const ITEM *item);
|
|---|
| 40 | .br
|
|---|
| 41 | .SH DESCRIPTION
|
|---|
| 42 | Every menu item has a field that can be used to hold application-specific data
|
|---|
| 43 | (that is, the menu-driver code leaves it alone). These functions get and set
|
|---|
| 44 | that field.
|
|---|
| 45 | .SH RETURN VALUE
|
|---|
| 46 | Except for \fBitem_userptr\fR (which returns \fBNULL\fR on error), each function returns one of the following:
|
|---|
| 47 | .TP 5
|
|---|
| 48 | \fBE_OK\fR
|
|---|
| 49 | The routine succeeded.
|
|---|
| 50 | .TP 5
|
|---|
| 51 | \fBE_SYSTEM_ERROR\fR
|
|---|
| 52 | System error occurred (see \fBerrno\fR).
|
|---|
| 53 | .SH SEE ALSO
|
|---|
| 54 | \fBcurses\fR(3X), \fBmenu\fR(3X).
|
|---|
| 55 | .SH NOTES
|
|---|
| 56 | The header file \fB<menu.h>\fR automatically includes the header file
|
|---|
| 57 | \fB<curses.h>\fR.
|
|---|
| 58 | .SH PORTABILITY
|
|---|
| 59 | These routines emulate the System V menu library. They were not supported on
|
|---|
| 60 | Version 7 or BSD versions.
|
|---|
| 61 |
|
|---|
| 62 | The user pointer should be a void pointer. We leave it as a char pointer for
|
|---|
| 63 | SVr4 compatibility.
