<div>
in unix scripts, you can reference $0 $1 $2 etc...<br />
<br />
in C (in unix) you have to define main as:<br />
void main(int argc; char **argv)<br />
the compiler will do the rest and you can reference the string with argv[0], argv[1] etc...<br />
<br />
to obtain these values outside of main, you must pass the strings as a parameter. to the function you're calling<br />

If your answer was a peremptory &quot;NO&quot; (explaining why) I would accept it. <br />
<br />
Obviously I could pass the argv parameter trough the program structure, but this does not appears to be &quot;clean&quot; programming.Instead I would prefer to declare a global variable and use it when needed.<br />
<br />
The question is :<br />
Is that global variable already defined in some include file ?<br />
<br />
Is there a system call that enables the capture of this information (processual info) ?<br />
<br />
Thanks anyway.

I accept that ! Although I am sorry !!!

With MSFT VC++ it is possible to obtain argv info trough a global variable defined in stdlib.g (__argv).<br />
<br />
Is there a similar way to obtain argv info outside of main in UNIX/C ?<br />
<br />
Thank you
