Hello all !
Could someone throw some light on whether there's a limit to the number of characters contained in the command string that is passed to the system() call in C.
Is it OS dependent? If yes, what are the limits for each?
Thanks. (4 Replies)

menu_mark(3X) menu_mark(3X)
NAME
menu_mark - get and set the menu mark string
SYNOPSIS
#include <menu.h>
int set_menu_mark(MENU *menu, const char *mark);
const char *menu_mark(const MENU *menu);
DESCRIPTION
In order to make menu selections visible on older terminals without highlighting or color capability, the menu library marks selected items
in a menu with a prefix string.
The function set_menu_mark sets the mark string for the given menu. Calling set_menu_mark with a null menu item will abolish the mark
string. Note that changing the length of the mark string for a menu while the menu is posted is likely to produce unhelpful behavior.
The default string is "-" (a dash). Calling set_menu_mark with a non-NULL menu argument will change this default.
The function menu_mark returns the menu's mark string (or NULL if there is none).
RETURN VALUE
The function menu_mark returns a pointer (which may be NULL). It does not set errno.
The function set_menu_mark may return the following error codes:
E_OK The routine succeeded.
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
E_SYSTEM_ERROR
System error occurred (see errno).
SEE ALSO
curses(3X), menu(3X).
NOTES
The header file <menu.h> automatically includes the header file <curses.h>.
PORTABILITY
These routines emulate the System V menu library. They were not supported on Version 7 or BSD versions.
