So you sit down at ???, which runs uxb3 -- which sounds more like a hostname than an OS to me -- and open a ??? terminal to run ??? to login to "toolman" which runs ???. Is it possible to run uname -a on any of these systems? Is it possible to fill in any of those question marks?
Yea, uxb3 is the hostname(uxb3.wiu.edu). I know it is Unix. I can access the school's Unix server from anywhere using any computer with the program Putty <PuTTY Download Page> .... which I then log in to "toolman"(which is also the hostname) using command "ssh toolman.wiu.edu" and can log in with my username/password for the school's system. I do not know if
works on any of the systems. I can get back to you with some betters answers about the actual systems by Monday when I can ask someone at the university's IT dept.

Nevermind, I made a typo here:
Quote:
printf("%s!\n", argv[1]);
In which, I forgot to type '\' after the exclamation point. Problem solved.

I am using a previous source code. I changed the main function main(int argc, char **argv) in a function misc(int argc, char **argv). How do you use the argc and argv parameters? This is how I am calling the function :

Is it possible to use the dbx debugger with the CL options for the executable ?
Say you have created a executable called myfunc which can take string arguments at run-time. You run it like this
./myfunc Hello World
where Hello and World are the string arguments
My question is whether... (1 Reply)
Hi C experts,
I have the following code for adding command line option for a program

Hello All,
First post. I've been struggling with the following:
Given a char* string, I need to construct an "int argc, char *argv" style structure. What I'm struggling with most is handling escaped-whitespace and quotes.
e.g. the string:
char *s = "hello world 'my name is simon'... (10 Replies)
when i run my program, i have a parameter, that i want to set the value to another string

}
and i get

All of my machines (various open source derivatives on x86 and amd64) store argv above the stack (at a higher memory address). I am curious to learn if any systems store argv below the stack (at a lower memory address).
I am particularly interested in proprietary Unices, such as Solaris, HP-UX,... (9 Replies)

arg
ARG(2) System Calls Manual ARG(2)NAME
ARGBEGIN, ARGEND, ARGC, ARGF, arginit, argopt - process option letters from argv
SYNOPSIS
#include <u.h>
#include <libc.h>
ARGBEGIN {
char *ARGF();
Rune ARGC();
} ARGEND
extern char *argv0;
/* Alef only */
Arg *arginit(int argc, byte **argv);
Rune argopt(Arg *arg);
byte *argf(Arg *arg);
DESCRIPTION
These macros assume the names argc and argv are in scope; see exec(2). ARGBEGIN and ARGEND surround code for processing program options.
The code should be the cases of a C switch on option characters; it is executed once for each option character. Options end after an argu-
ment --, before an argument -, or before an argument that doesn't begin with -.
ARGC() returns the current option character.
ARGF() returns the current option argument: a pointer to the rest of the option string if not empty, or the next argument in argv if any,
or 0. ARGF must be called just once for each option that takes an argument.
After ARGBEGIN, argv0 is a copy of argv[0] (conventionally the name of the program).
After ARGEND, argv points at a zero-terminated list of the remaining argc arguments.
Alef
The Alef argument processing routines are unrelated. Instead, an aggr called Arg is initialized by a call to arginit. Successive calls to
argopt return successive option characters, or zero at the end of the options. After a call to argopt, argf will return any argument
string associated with the option.
EXAMPLES
This C program can take option b and option f, which requires an argument.
#include <u.h>
#include <libc.h>
void
main(int argc, char *argv[])
{
char *f;
print("%s", argv[0]);
ARGBEGIN {
case 'b':
print(" -b");
break;
case 'f':
print(" -f(%s)", (f=ARGF())? f: "no arg");
break;
default:
print(" badflag('%c')", ARGC());
} ARGEND
print(" %d args:", argc);
while(*argv)
print(" '%s'", *argv++);
print("
");
exits(0);
}
Here is the output for the run prog -bffile1 -r -f file2 arg1 arg2
prog -b -f(file1) badflag('r') -f(file2) 2 args: 'arg1' 'arg2'
This Alef program accepts options b and, with an attached file name, f.
#include <alef.h>
void
main(int argc, byte **argv)
{
int a, ac, bflag;
byte *file;
Arg *arg;
arg = arginit(argc, argv);
while(ac = argopt(arg)) switch(ac){
case 'b':
bflag = 1;
break;
case 'f':
file = argf(arg);
break;
}
for(a=0; a<arg->ac; a++)
print("argument %s
", arg->av[a]);
}
