Hi,

The following program crashes on suse-ppc. I am trying to copy the command line parameters to a string buffer. I tried this on suse i386 and its working fine. Its crashing on suse-ppc.

#include #include

main(int argc, char *argv[]) { char Buffer[1024]; va_list ap; //ap = argv; //works fine on i386 va_copy(ap,argv); // cant use ap = argv on ppc. Need to use va_copy vsprintf(Buffer,"Command Line arguments: %s\n",ap); printf("%s", Buffer); }

Please help me in resolving this.

The argv array is not a variable argument list. You will have to use a for(i=1;i

This code is just a sample code that I have written to illustrate the problem. I need to convert the command line arguments into a va_list. I tried using "ap =argv;". But this is not allowed on ppc. So I am using "va_copy" to copy the contents of argv into ap. This is the main purpose. However when I use ap with vsprintf, the application is crashing.

Please provide a real usable example hello_world.c There is nothing wrong with va_args, unless proven otherwise.

Thanks Marcus, Appy. Marcus Meissner wrote: On Mon, Oct 30, 2006 at 02:27:54AM -0800, appy 80 wrote:

I am afraid it is not possible. va_list are created by the compiler on a varargs function call, you cannot do it programmaticaly. Ciao, Marcus --------------------------------- Want to start your own business? Learn how on Yahoo! Small Business.
