libc struct termios <--> kernel struct termios, how?

[Franz Sirl]

Hi,

while investigating an ioctl() "invalid argument" in top (from
procps-1.2.7) on glibc-2.0.93/powerpc, I wondered what's the correct
include file for 'struct termios' and 'TCGETS'. top currently includes
<termios.h>, but the definition there differs from from the kernel
definition (NCCS is 32 resp. 19). Since sizeof(struct termios) is coded
into TCGETS, top will use a value for TCGETS which is not understood by the
kernel.

What is the correct solution for that? Using <asm/termios.h>?

Thanks,
Franz.
