Hi...

i would like to know how to copy a string such as
"Test" to a char vector (char buffer[256]) in kernel
mode.

Thanks,
Luis Henrique.

Example from  arch/i386/kernel/kgdb_stub.c:


#include <asm/string.h>         /* for strcpy */

static char remcomOutBuffer[BUFMAX];

strcpy(remcomOutBuffer, "OK");

Hope it's ok.

Not really. Well, this example here works, but only if you know that you
won't overflow the buffer.

strlcpy(emcomOutBuffer, "OK", BUFMAX);

(replace "OK" with the string you wish to copy)

Do the make modules_install. The new modules will be in a separate directory 
(/lib/modules/<version>) and will not interfere with older kernels that you 
might have.

Hi Guys,

I would like to know when a compiling the kernel if a
really need to use the comand make modules_install.
I'm asking the question because a would like to use
the old kernel to with the new one that a create.
