In this case I generally create a data structure that has all of the information that needs to be passed to the thread and pass it in. The value of argv and argc would be included in the struct.
The easy way is to create two global variables
You then can assign argv and argc to them, and reference them in your threads. I'm not a big fan of globals, but this works.
i just finished a project for a c++ class that i wrote at home on my computer, compiled with gcc. when i brought the code into school it would not compile, it would complain that cannot call main() function. at school we use ancient borland c++ from 1995. anyway my program has 20 different...

Hi,
I have a main loop which calls a sub loop, which finally returns to the main loop itself. The main loop runs when a flag is set. Now, I have a signal handler for SIGINT, which resets the flag and thus stops the main loop. Suppose I send SIGINT while the program is in subloop, I get an error... (1 Reply)

H friends,
As we know, a function returns a value and that value is saved somwhere. like
int Sum( int x, int y )
{
return x + y;
}
Total = Sum( 10, 20 );
The value 30 is saved in variable Total.
Now the question is, what int value does the function main return, and where is it... (5 Replies)
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)
I feel that i am missing something obvious but i can't find what is wrong.
I have a script that is launching some functions with "&" and each call is feeding the array with a value. When all calls are finished I just want to retrieve the values of that array.
It is looking like that :

A sample.c file is written with only one single statement.
main;
Segmentation fault occurred when executed that file.
Any statement other than main; is written, for example unix; then it won't compile.
why is this behaviour ! (2 Replies)

tcl_concat
Tcl_Concat(3) Tcl Library Procedures Tcl_Concat(3)__________________________________________________________________________________________________________________________________________________NAME
Tcl_Concat - concatenate a collection of strings
SYNOPSIS
#include <tcl.h>
CONST char *
Tcl_Concat(argc, argv)
ARGUMENTS
int argc (in) Number of strings.
CONST char * CONST argv[](in)
Array of strings to concatenate. Must have argc entries.
_________________________________________________________________DESCRIPTION
Tcl_Concat is a utility procedure used by several of the Tcl commands. Given a collection of strings, it concatenates them together into a
single string, with the original strings separated by spaces. This procedure behaves differently than Tcl_Merge, in that the arguments are
simply concatenated: no effort is made to ensure proper list structure. However, in most common usage the arguments will all be proper
lists themselves; if this is true, then the result will also have proper list structure.
Tcl_Concat eliminates leading and trailing white space as it copies strings from argv to the result. If an element of argv consists of
nothing but white space, then that string is ignored entirely. This white-space removal was added to make the output of the concat command
cleaner-looking.
The result string is dynamically allocated using Tcl_Alloc; the caller must eventually release the space by calling Tcl_Free. |
