  32. .SH NAME
  33. \fBmenu_mark\fR - get and set the menu mark string
  34. .SH SYNOPSIS
  35. \fB#include <menu.h>\fR
  36. .br
  37. int set_menu_mark(MENU *menu, const char *mark);
  38. .br
  39. const char *menu_mark(const MENU *menu);
  40. .br
  41. .SH DESCRIPTION
  42. In order to make menu selections visible on older terminals without
  43. highlighting or color capability, the menu library marks selected items
  44. in a menu with a prefix string.
  45. .PP
  46. The function \fBset_menu_mark\fR sets the mark string for the given menu.
  47. Calling \fBset_menu_mark\fR with a null menu item will abolish the mark string.
  48. Note that changing the length of the mark string for a menu while the
  49. menu is posted is likely to produce unhelpful behavior.
  50. .PP
  51. The default string is "-" (a dash). Calling \fBset_menu_mark\fR with
  52. a non-\fBNULL\fR menu argument will change this default.
  53. .PP
  54. The function \fBmenu_mark\fR returns the menu's mark string (or \fBNULL\fR if
  55. there is none).
  56. .SH RETURN VALUE
  57. The function \fBmenu_mark\fR returns a pointer (which may be \fBNULL\fR).
  58. It does not set errno.
  59. .PP
  60. The function \fBset_menu_mark\fR may return the following error codes:
  61. .TP 5
  62. .B E_OK
  63. The routine succeeded.
  64. .TP 5
  65. .B E_BAD_ARGUMENT
  66. Routine detected an incorrect or out-of-range argument.
  67. .TP 5
  68. .B E_SYSTEM_ERROR
  69. System error occurred (see \fBerrno\fR).
  70. .SH SEE ALSO
  71. \fBcurses\fR(3X), \fBmenu\fR(3X).
  72. .SH NOTES
  73. The header file \fB<menu.h>\fR automatically includes the header file
  74. \fB<curses.h>\fR.
  75. .SH PORTABILITY
  76. These routines emulate the System V menu library. They were not supported on
  77. Version 7 or BSD versions.
