Kernel alternative for vsprintf


Can anyone tell me what to use instead of command vsprintf while coding for a Kernel level USB device driver.

The function : int vsprintf(char *str, const char *format, va_list ap); works only at user level coz the file stdio.h has to be included. but this file is not available at kernel level. I'm stuck with this problem.

What other function can i use which uses the same parameters and does the same job of formatted printf.

Hmm... the kernel is chock-full of examples. They build up the string in a buffer piece by piece.
